Detection of High Rate STBC in Frequency Selective m- Nakagami Fading Environment

چکیده
In this article, we concerned with the performance of high rate space time block code (STBC) scheme for Frequency selective fading Environment. Due to large channel delay spread in Frequency selective channel inter symbol interference (ISI) occurred. In high rate STBC, ISI occurs due to loss of „quasi – static‟ assumption and Classical Zero forcing (ZF) receiver produces error floor in Bit error rate (BER) performance. In this article we evaluate and proposed low Complexity Zero forcing which reduce the complexity of receiver for detection of high rate STBC and evaluate the performance in m–Nakagami fading environment. KeywordsSpace time block code (STBC), Inter symbol interference (ISI), Zero forcing (ZF).

Single-Carrier Frequency-Domain Equalization for Orthogonal STBC over Frequency-Selective MIMO-PLC channels
In this paper we propose a new space diversity scheme for broadband PLC systems using orthogonal space-time block coding (OSTBC) transmission combined with single-carrier frequency-domain equalization (SC-FDE). To apply this diversity technique to PLC channels, we first propose a new technique for combining SC-FDE with OSTBCs applicable to all dispersive multipath channels impaired by impulsive...

ELECT The symbol pairwise error probability performance of the Alamouti space-time block code (STBC-Alamouti) and the STBC from the coordinate interleaved orthogonal design (STBC-CIOD) over Nakagami-m fading channels is investigated, especially with residual phase estimation error (PEE). The derived union upper bounds on the average BER are utilised to evaluate the effect of the residual PEE on...

متن کاملFrequency-Domain Equalization for Single-Carrier Space-Time Block Coded Transmit Diversity in a High Mobility Environment
Single-carrier (SC) transmission with space-time block coded (STBC) transmit diversity can achieve good bit error rate (BER) performance. However, in a high mobility environment, the STBC codeword orthogonality is distorted and as consequence, the BER performance is degraded by the interference caused by the orthogonality distortion of STBC codeword. In this paper, we proposed a novel frequency...
