Optimization of Layered Space Time Codes for MIMO Underwater Sensor Communication
Abstract— In this paper, we expand iterative turbo equalizer techniques for single-input-single-output
(SISO) system to multiple-input-multiple-output (MIMO) system in order to increase data rates for
multipath channel environment such as underwater communication channel. In MIMO system, space
time trellis codes (STTC) was employed as an inner code. In receiver side, BCJR algorithm is used
for STTC decoding in order to improve BER performance by increasing iterations. Based on
experimental channel response, we confirmed that the performance is the better as iteration number is
increased.
