First, a linear MMSE (LMMSE) technique for MIMO-FBMC channel estimation, which require a priori knowledge of channel correlation matrix, is examined by utilizing the second-order statistical properties of the intrinsic interference in FBMC systems. A biased LS (BLS) and relaxed LMMSE (RLMMSE) MIMO-FBMC channel estimation schemes, which require prior knowledge of the trace of the channel correlation matrix, are proposed. The LS-BLS and LS-RLMMSE schemes for MIMO-FBMC channel estimation are investigated in the presence of imperfect knowledge of the channel correlations. The mean square error is derived for the proposed schemes by exploiting statistical properties of the intrinsic interference. Simulation results show that the proposed schemes present an excellent trade-off between the achieved performance and required a priori knowledge of the channel correlations.","PeriodicalId":6870,"journal":{"name":"2019 National Conference on Communications (NCC)","volume":"40 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77993960","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 new data mapping scheme (DMS) is suggested for the proposed serial pipelined FFT architecture. The performance is enhanced by performing FFT computations in $log_{2}N-1$ stages followed by a select-store-feedback (SSF) stage, where $N$ is the number of points in FFT. Further enhancement in performance is achieved by employing quarter-complex multiplierless unit made up of memory and combinational logic in every stage. The memory stores half number of partial products while the remaining partial products are taken care by external combinational logic. Compared with the best existing scheme, the proposed design reduces the computational workload on half-butterfly (H-BF) units by $(2N-8)$. Application specific integrated circuit (ASIC) and field programmable gate array (FPGA) results show that the proposed design for 1024-point achieves 31.54% less area, 30.13% less power, 33.56% less area-delay product (ADP), 27.11% less sliced look-up tables (SLUTs) and 28.37% less flip-flops (FFs) as compared to the best existing scheme.","PeriodicalId":6870,"journal":{"name":"2019 National Conference on Communications (NCC)","volume":"6 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85421894","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}

Panigrahi","doi":"10.1109/NCC.2019.8732188","DOIUrl":"https://doi.org/10.1109/NCC.2019.8732188","url":null,"abstract":"Among several in-home communication systems, broadband over power line communication (BB-PLC) provides better connectivity at cheaper installation cost without disturbing the existing infrastructure. Conventional broadband systems, including BB-PLC, use the orthogonal frequency division modulation (OFDM) to combat the issue of frequency selective fading at the cost of extra bandwidth. However, it is proposed and shown that the spectral efficiency of the OFDM can be improved either by using filter bank multi-carrier (FBMC) or filtered OFDM (F-OFDM). In the former, all the sub-carriers of an OFDM symbol are filtered, however, in the latter, only the final OFDM symbol is filtered. Thus, it is a cost-effective solution to use the F-OFDM over the FBMC. This paper presents the hardware implementation of the F-OFDM for BB-PLC. Different prototype low-pass filters are used for comparative analysis, especially for the BB-PLC. The simulations are carried out in National Instruments' LabVIEW software and the hardware implementation of the transceiver is done on National Instruments' Software Defined Radio (SDR) set called USRP 2920. Polycab 1.5 SQ mm home wiring power cable is used as the communication channel in testing the BB-PLC system. From the power spectral density analysis, it is concluded that the F-OFDM has better spectral efficiency than the conventional OFDM. Further, it is observed that as the length of the filter increases the better spectral efficiency is achieved but at the cost of increased complexity.","PeriodicalId":6870,"journal":{"name":"2019 National Conference on Communications (NCC)","volume":"31 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75447993","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}
