Abstract :
A novel union detection algorithm based on the iterative cyclic QR decomposition (IQRD) algorithm and Bi-Directional ZF (BED-ZF) algorithm is proposed in this paper. By combining the advantage of BID with the IQRD, the proposed algorithm overcomes the error propagation of the conventional QR algorithm and the performance is improved effectively. Simulation results show that the proposed BID-IQRD algorithm is superior to the pure IQRD algorithm and BID-ZF algorithm.
