Abstract

We provide a new detection scheme for interference nulling and cancellation operation in a vertical Bell laboratories layered spacetime (VBLAST) system to reduce unexpected effects due to parallel transmission in this paper. This method can reduce the time delay as well as moderate the multipath fading effect. We will show that the performance of investigated VBLAST detection based on hybrid processing performs better than ordinary VBLAST detections based on successive and parallel processing, respectively.
