Abstract :
In this paper, the low-complexity near-optimal (LCNO) detector and code design for the generalized space-time shift keying (G-STSK) scheme are studied. First, the LCNO randomized bitwise Markov chain Monte Carlo (R-b-MCMC) detector is presented. Next, the low-density parity-check code is optimized based on the extrinsic-information transfer chart technique. Simulation results are provided to demonstrate the performance of the proposed detector and the optimized code.
