Performance Analysis of an Improved Signal Detection Based on SDQR Decomposition Algorithm

Abstract

This paper proposes an improved QR signal detection, which is based on SDQR decomposition algorithm. VBLAST is an effective detection method for MIMO OFDM systems, but has a large computational complexity. Performance analysis of OR algorithm and other algorithms (such as ZF, QR, ML....) in Rayleigh channel is carried on and the result shows that SDQR decomposition algorithm has better performance.
