The roots of ICSPCS go back to a series of successful symposia and workshops, namely, the International Symposia on DSP and Communication Systems (DSPCS), and Workshops on the Internet, Telecommunications and Signal Processing (WITSP). Accordingly, the topics covered by ICSPCS stretch over the entire protocol stack of modern telecommunication systems from the physical and data link layers to networking and application layers along with the related processing, applications, and services. The technical program for this year covers a range of topics such as wireless communications, communications theory, communication systems, networks and protocols, information and network security, localization and tracking, signal processing for multimedia and communications, and medical applications. One of the main goals of this international conference is to bring together researchers and scientists from academia and industry that work in the aforementioned areas to present and discuss their latest research results, explore new ideas and solutions, and to facilitate networking among colleagues. As in the previous years, the Organizing Committee has succeeded in achieving an official technical co-sponsorship of the IEEE Communications Society for the conference. As a result, ICSPCS'2012 has been listed in the IEEE database of conferences and the proceedings will be published in IEEEXplore.","PeriodicalId":261348,"journal":{"name":"International Conference on Signal Processing and Communication Systems","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133698799","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}

Nevertheless, to achieve such a superior performance, it needs to repeat a probabilistic decoding operation over each corrupted data block for several times and thus exhibits considerable decoding latency. A decoding latency as such may forbid possible cost reduction on designing a communication receiver, especially when a strict round-trip latency is specified. This paper proposed a Turbo Decoding scheme which benefits from the diversity characteristic provisioned by some communication systems, and thus is able to efficiently reduce required decoding latency thereof. To verify the performance, the popular Max-Log-MAP algorithm has been cascaded with the proposed scheme and is simulated with a range of AWGN conditions. Possible alternatives to the proposed scheme are also presented while the trends of the resource utilization and the BER performance are presented and discussed. As the experimental result shows, the proposed Turbo decoding schemes can introduce at least 4x latency reduction comparing to the traditional scheme, while preserving an adequate decoding performance.","PeriodicalId":261348,"journal":{"name":"International Conference on Signal Processing and Communication Systems","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114247797","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}

A class of algorithms facilitating this task are iterative methods such as the well-known iterative decoding of turbo codes or low density parity check codes. But also iterative equalization methods become more and more important in praxis. Usually, the signal processing for these iterative methods is realized with digital hardware. Besides all its advantages, a major drawback of digital signal processing is the large power consumption, especially for high data rates. The fundamental structure underlying iterative interference cancellation algorithms is a recurrent neural network (RNN). Recently, it has been shown that an iterative decoding algorithm based on belief propagation can be represented by a generalized RNN. Taking the original work of Hopfield as a starting point, we propose an analog electronic circuit which resembles a generalized RNN. Compared to digital signal processing, analog signal processing allows to perform iterative decoding or equalization with increased computational speed and reduced chip area and power consumption.","PeriodicalId":261348,"journal":{"name":"International Conference on Signal Processing and Communication Systems","volume":"181 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122233610","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}

One of the best solutions to support the maximum data rate transmission is to adopt a MIMO scheme, especially spatial multiplexing mode, which means that each antenna port can transmit separate data. To realize this algorithm, the main issue is to cancel interferences added to each antenna port, and therefore, the algorithm at the receiver should have good performances. In the aspect of implementation, MMSE (Minimum Mean Square Error) detection algorithm is a reasonable method considering both complexity and performance. Furthermore, an iterative receiver (IR) algorithm can also be applied to this system. An IR algorithm has a tradeoff between complexity and performance. In this paper, we designed a reasonable and implementable MIMO receiver structure and showed performance for 3GPP LTE Advanced system, and verified that hard decoded bits, PIC-MMSE (Parallel Interference Cancellation - MMSE) and 1-iteration PIC are enough to meet the required SNR using the implemented test-bed system.","PeriodicalId":261348,"journal":{"name":"International Conference on Signal Processing and Communication Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131081325","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}
