The high computational resources demand of SDRs has enforced in the past the use of dedicated chips and special purpose hardware, such as digital signal processors (DSPs) and field-programmable gate arrays (FPGAs). The last years Graphics Processing Units (GPUs) are excelling in the areas where FPGAs and DSPs used to dominate. Unavoidably, the use of GPUs has been proposed for SDR processing unit, but not in the most efficient way. We propose and implement, using off-the-shelf components, an efficient, direct GPU-to-SDR communication scheme, and we provide insights for more efficient utilization of the GPU processing power.","PeriodicalId":184216,"journal":{"name":"Proceedings of the 2015 Workshop on Software Radio Implementation Forum","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130877672","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our goal is to develop a flexible infrastructure that allows FPGA-based processing to be combined with CPU-based processing. Our conclusions are that there is little difference in area or performance between NoC organizations, particularly for a small number of processing endpoints, that some space is saved by time-interleaved signal processing blocks but that partial reconfiguration is likely to lead to gross inefficiencies. Based on this experience, we are focusing our FPGA design effort on developing software that can simplify and automate the process of developing SDR signal processing chains. This software relies on standard interfaces and a synthesis as a service organization to reduce the complexity of constructing custom FPGA bitfiles rather than mechanisms to dynamically reconfigure FPGA's.","PeriodicalId":184216,"journal":{"name":"Proceedings of the 2015 Workshop on Software Radio Implementation Forum","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131954873","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, single layer performance improvements are decreasing compared to cross-layer optimizations. These optimizations have more degrees of freedom and therefore allow for greater improvements. Sadly, there are no platforms that allow easy prototyping of these cross-layer optimized systems. To tackle this problem we present CLAWS (Cross-Layer Adaptable Wireless System), which combines a powerful FPGA based SDR with a fully standard compliant IEEE 802.15.4 stack. Combined to form a very flexible platform with easy access to all layers of the network stack. To show its performance we have developed a demonstrator that shows how CLAWS can interoperate with a network of off-the-shelf wireless sensor nodes. Moreover, using this powerful and easy to use platform, we've implemented a cross-layer improvement, where all nodes are able to send on different frequencies at the same time to the CLAWS node.","PeriodicalId":184216,"journal":{"name":"Proceedings of the 2015 Workshop on Software Radio Implementation Forum","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132590585","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Existing approaches for dealing with such cross technology interferences require either at least one preamble is clean or at least one signal is decoded correctly. However, uncooperative cross technology users and unpredictable interference call for innovative cross technology coexistence. This paper proposes a novel design that enables node resolve cross technology interference. By exploiting frequency diversity, our approach can recover the CSI (channel state information) of both signals even when they are corrupted by each other. Moreover, with iterative interference cancellation, our approach can recover the both corrupted signals without decoding one of the signal correctly. We implement the proposed scheme on USRP/GUN radio platform. Experimental results show that our method can recover the CSI when there is no clean preamble of either and the iterative interference cancellation can effectively decode both signals.","PeriodicalId":184216,"journal":{"name":"Proceedings of the 2015 Workshop on Software Radio Implementation Forum","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133130882","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It provides a hardware abstraction layer with a consistent API for the user space applications. As of today, the IIO framework consists of approximatively 200 drivers, of which many handle multiple devices. It supports discrete components as well as integrated transceivers like the Analog Devices AD9361, a 2 x 2 RF Agile Transceiver, found in many SDR products. Recently, Analog Devices created several new blocks for GnuRadio that can be used to stream samples from and to high-speed IIO devices. Adding a few signal processing blocks, it becomes very easy to create complex applications such as LTE or IEEE 802.11g OFDM receivers, radar processing, or just simple applications like wide-band FM transceivers. This demo will focus on presenting the IIO blocks for GnuRadio; how they can be used, their functionalities, the controls they provide over the hardware. For this purpose, the demo will be a GnuRadio flowgraph that corresponds to a IEEE 802.11g (WiFi) packet sniffer, which has the advantage of showing a real-world use case of a fast (20 MHz sample rate) software defined radio application, while remaining relatively simple with only a handful of blocks.","PeriodicalId":184216,"journal":{"name":"Proceedings of the 2015 Workshop on Software Radio Implementation Forum","volume":"75 10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126018835","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Already today we are surrounded by a vast amount of simple low data rate wireless systems.

Most recently, car and plane manufacturers started replacing wired sensors with wireless systems to save cabling and, thus, weight and fuel. Typically, frame-based single carrier systems are used. These rely on a preamble for synchronizing to the signal followed by a Start of Frame Delimiter (SFD) and the actual data.
