Abstract
A novel parallel iterative cycle QR decomposition detection algorithm in VBLAST-OFDM system is proposed in this paper. In order to overcome the disadvantage of the poor performance of the first detected layer in IQRD algorithm, the parallel detection is applied to the IQRD algorithm and the performance is improved effectively. Simulation results show that the proposed P-IQRD algorithm is superior to the IQRD algorithm.
