Title
An Improved Mixed Gibbs Sampling Algorithm Based On Multiple Random Parallel Markov Chains For Massive Mimo Systems
Abstract
Massive MIMO can significantly improve diversity/multiplexing gain, channel capacity and spectrum efficiency. An efficient signal detection algorithm plays a very important role for system performance. However, the BER, complexity and delay performance of present signal detection algorithms are far from optimal with the increasing number of antennas. This paper presents an improved mixed Gibbs sampling algorithm based on multiple random parallel markov chains (MGS-MRPMC). It has lower complexity than traditional signal detection algorithms in massive MIMO systems. The simulation shows that the proposed algorithm can alleviate the stalling problem encountered in the mixed Gibbs sampling (MGS) algorithm with higher order QAM. Moreover, it can reduce the serious delay of the mixed Gibbs sampling with multiple restarts (MGS-MR) algorithm. The use of parallel strategy makes it suitable for hardware implementation in practice.
