Abstract :
A detection of joint QR decomposition and partial sphere decoder (JQRPSD) method with low complexity is proposed in this paper. The purpose of the detection is reducing complexity from sphere decoder and having better performance than successive cancellation detection with QR decomposition (QR-SCD) and vertical Bell laboratories layered space-time (V-BLAST). In a perfect channel estimated receiver, the simulation of JQRPSD method performs the performance approaching the performance of sphere decoder algorithm. The proposed detector is designed by TSMC 0.18 mum CMOS technology without preprocessor in 4 x 4 multiple input and multiple output (MIMO) wireless communication.
