Two are the benefits of including this equalizer in a repeater setup: on one hand, the transmitted signal requires a lower dynamic range and its degradation becomes smaller at the output amplifiers, thus allowing for a higher transmit power for the same modulation error rate (MER). On the other hand, it eases the equalization and decoding processes at the final receiver by improving its operation conditions. In this context, we present a novel low-cost equalizer architecture for mid-range and domestic gap-fillers. The design, implementation and validation methodology is also described, from the initial Matlab and advanced design system (ADS) simulations to the final hardware implementation, based on a field programmable gate array (FPGA) device and a Blackfin digital signal processor (DSP). The obtained practical results assess the performance gains predicted by simulation, hence proving the validity and efficacy of the designed equalizer to reduce the cost of the amplifiers and to obtain a better signal quality at the final userpsilas receiver.","PeriodicalId":105399,"journal":{"name":"2008 Third International Conference on Systems and Networks Communications","volume":"109 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121741485","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}

In particular, we propose a joint coded two-step interference cancellation scheme which effectively combats the effect of co-channel interference (CCI) and inter-symbol interference (ISI) in multipath channels. To overcome the peak-to-average-power ratio limitation of multicarrier systems, the scheme employs single-carrier frequency-domain equalization (SC-FDE) based modulation combined with time-reversed space-time block codes (TR-STBC). The receiver performs minimum mean-squared error (MMSE) interference suppression at the first stage, and then, CCI cancellation is implemented with a bank of single-user channel decoders. Also, forward error correction outer convolutional encoding, and random bit interleaving are used to correct the carrier in deep fades. To verify the utility of the proposed approach, the paper also includes two sets of average symbol error rate simulations for two different channel models. The first set is for a frequency selective quasi-static fading channel while the secondset is for a Rayleigh fading channel modeled by a modified Jakes' model, both of which confirm the advantage of the proposed scheme.","PeriodicalId":105399,"journal":{"name":"2008 Third International Conference on Systems and Networks Communications","volume":"188 9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132281491","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}
