Parallel Iterative Cycle QR Factorization Detection Algorithm based on VBLAST-OFDM
Hongliang Fu · Communications technology · 2009
A novel parallel iterative cyclic QR decomposition detection algorithm based on VBLAST-OFDM system is proposed in this paper. In order to overcome the disadvantage of the poor performance for the first detected layer in IQRD algorithm, the parallel detection is applied to the IQRD algorithm, thus the error propagation is further suppressed and the performance is effectively improved. Simulation results show that the proposed P-IQRD algorithm is superior to the IQRD algorithm, the conventional parallel algorithm, the ZF algorithm and the QR decomposition algorithm.
