Space Time Block Coding for MIMO Systems With Low Decoding Complexity
Journal Title: International Journal of Electronics Communication and Computer Technology - Year 2013, Vol 3, Issue 6
Abstract
MIMO systems with multiple antenna elements at both link ends are an efficient solution for future wireless communications systems as they provide high data rates by exploiting the spatial domain under the constraints of limited bandwidth and transmit power. Space-Time Block Coding (STBC) is a MIMO transmit strategy which exploits transmit diversity and high reliability. This paper presents a detailed study of Different space-time block coding (STBC) schemes including Alamouti’s STBC for 2 transmit antennas and 1 receive antennas as well as orthogonal STBC for 4 transmit antennas and 1 and 2 receive antennas are explored. Orthogonal space–time block codes (OSTBC) from orthogonal designs with maximum-likelihood (ML) decoding achieve low decoding complexity and full diversity. Finally, these STBC techniques are implemented in MATLAB. And ccomparative analysis for performance according to their bit error rates using M-ary PSK, QPSK, QAM, modulation schemes at the transmitter side in a Raleigh fading channel.
