More throughput and better radio coverage w.r.t. former standards are examples of mandatory improvements. Generally, a new standard consists in modifying elements of the systems incrementally: add a receive antenna, use higher order modulation, etc. The design methodology is then crucial to ensure system quality while maintaining a short time for delivery. This paper proposes to use dataflow modelling for its ability to represent complex systems at a high level of abstraction. The dataflow representation inputs a 2-step incremental design method that aims at ensuring perfect compliance to quality requirements. The method consists first in sizing interfaces and then defining process accuracy to reach the desired quality. The studied use case is a High Speed Downlink Packet Access (HSPDA) receiver type 2 where the channel equalizer replaces the RAKE receiver on an existing system. We show that the fast prototyping can be done by focusing only on the key blocks to reduce time-to-design. The fixed-point refinement is studied thoroughly and we show the quality constrained of 2.31 dB is maintained all through the design steps. It ensures performance independence to run simulations in parallel and keep the time-to-design reasonable.","PeriodicalId":167156,"journal":{"name":"2014 IEEE Workshop on Signal Processing Systems (SiPS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131146294","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}

This paper proposes two schemes to address multi-way channels when a set of terminals wants to exchange data. Both proposed schemes consist of a first phase based on virtual MIMO with lattice reduction-aided (LRA) detection at the relay, establishing a multiple access channel (MAC). Two new strategies are then proposed for the second (multicast) phase; one for single antenna terminals and another for multiple-input multiple-output (MIMO) terminals. The second strategy achieves interference suppression by successively combining physical layer network coding and MIMO detection (with LRA detectors also at the terminals). The paper assesses a 3 terminals network with a relay for which a TDMA-based scheme would require 6 time-slots, while the proposed strategy for MIMO terminals is able to exchange the information between all terminals using 2 time-slots only. This latter scheme is easily scalable to a higher number of terminals, and always able to accomplish the exchange of messages between all of them in just 2 time-slots, although limited by the number of antennas that the terminals can fit and also the MIMO processing complexity they can afford.","PeriodicalId":167156,"journal":{"name":"2014 IEEE Workshop on Signal Processing Systems (SiPS)","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121877240","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, MSE is vulnerable to trends. Ensemble empirical mode decomposition (EEMD) is a powerful tool to remove the trend from non-stationary physiological signals before MSE analysis. In this paper, trend-extracted MSE (T-MSE) based on adaptive aligned EEMD (AA-EEMD) with early termination scheme is proposed. AA-EEMD not only reduces the computing time, but also considers the frequency meaning of different physiological signals and different subjects. We have applied T-MSE based on AA-EEMD to analyze the acute stroke patients' physiological signals in intensive care unit (ICU). We find that the complexity of electrocardiogram (EKG) is higher in the acute stroke patients with good functional outcome than those with bad functional outcome. For EKG parameter, the p-value is approximately 10-8, which shows significant statistical difference. Moreover, the average number of IMFs in a single member of ensemble is reduced to 74% of the original. The average computing time in a single member of ensemble is reduced to 76%. Also, the average computing time of combining EEMD and MSE is reduced to 72%.","PeriodicalId":167156,"journal":{"name":"2014 IEEE Workshop on Signal Processing Systems (SiPS)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116398493","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}
