Space-Time Block Coded (STBC) In-phase Quadrature-phase (IQ)-interleaved Coded Modulation (CM) schemes are proposed for Orthogonal Frequency Division Multiplexing (OFDM). Trellis Coded Modulation (TCM), Turbo TCM (TTCM), Bit-Interleaved Coded Modulation (BICM) and Iteratively Decoded BICM (BICM-ID) schemes having a similar decoding complexity are employed in conjunction with 16-level Quadrature...

We analyze the exact average symbol error probability (SEP) of binary and M-ary signals with spatial diversity in Nakagami-q (Hoyt) fading channels. The maximal-ratio combining and orthogonal space-time block coding are considered as diversity techniques for single-input multiple-output and multiple-input multiple-output systems, respectively. We obtain the average SEP in terms of the Lauricell...

Recently, there has been an explosion of growth in research on MIMO (Multiple Input Multiple Output) systems. Current WLAN systems such as IEEE 802.11a and 802.11g Wireless Local Area Networks (WLANs) employ Coded Orthogonal Frequency Division Multiplexing (COFDM) and provide data rates of up to 54 Mbps in a 20MHz bandwidth. In this paper, space-time block coding (STBC) and spatial multiplexing...

We examine a two–rate communication system where the transmission is suspended if the received SNR falls below a given threshold. We assume an FDD system and derive novel closed–form bit error probabilities in the presence of feedback errors in flat Rayleigh fading environment for single antenna transmission, orthogonal space–time block coding and transmit antenna selection. A single–user two–r...

In this paper, a comprehensive study has been made to evaluate the performance of a MISO wireless communication system. The 4-by-1 spatially multiplexed Turbo encoded system under investigation incorporates Quasi-orthogonal space-time block coding (Q-STBC) and ML signal detection schemes under QPSK, QAM, 16PSK and 16QAM digital modulations. The simulation results elucidate that a significant im...
