Advanced SD Iterative DecodingAlgorithm in MIMO Reciever
STBC-OFDM systems provide diversity and coding gains,however ,ML(Maximum Likelihood) has expensive computational complexity,which can not satisfy the need of high-velocity and real-time communication system. This paper presents a sphere decoding algorithm which finds a method of searching new vector in a sphere radius.We also present a new better searching method based on re-ordered vectors in complex field.This approach optimizes sphere radius iteration,increases the searching speed of signal vector. Compared with other algorithms,the result of simulation shows superiority on computational complexity and increases the efficiency of decoding.
