Abstract :
New sphere decoding algorithms are proposed in this paper. We put the emphasis on an iterative list branch and bound (BB) algorithm which is based on the basic BB algorithm.. When compared to other LSD algorithms, simulation results show that the proposed list BB algorithm can achieve near capacity performance with smaller candidate list size.
