We analyze a sub-optimum transmit antenna selection (TAS) scheme in multiple input single output (MISO) systems equipped with I transmit antennas. We keep one antenna fixed and select the best among the remaining N - 1 antennas. We assume spatially independent flat fading channel with perfect channel state information (CSI) at receiver and an ideal feedback link. We use Alamouti transmit diversity...
The V-BLAST (Vertically-layered Bell Laboratories Layered Space-Time) algorithm is a multilayer symbol detection scheme. The proposed work focuses on V-BLAST technique with a Multiple Input Multiple output (MIMO) technology followed by receiver detection techniques like Zero forcing (ZF), Minimum Mean Square Error (MMSE) with back substitution SIC (Symbol Interference Cancellation). The proposed methodology...
In this paper we investigate the performance of IEEE 802.16-2005 OFDMA system with high order QAM/QPSK mapping in the presence of high SNR values that are found both in Urban and Rural Environments. We consider OFDMA scheme with an AWGN channel and analyze their performance in terms of the BER in the system.
The instantaneous SNR (signal to noise ratio) of the receiver of STBC (space-time block codes) over Rayleigh fading channels is illustrated, based on this, the closed impression of STBC's BER (bit error rate) is deduced with M-PSK modulation. Based on the model of STBC in MIMO (multiple-input multiple-output) system, the numerical simulation and the analysis are presented.
