This paper will analyse the RLS algorithm and its improved algorithms, QRD-RLS and IQRD-RLS algorithms. QRD-RLS and IQRD-RLS algorithms can reduce the complexity of RLS algorithm effectively. Then, we apply these three algorithms in MIMO-OFDM system, and we do some simulations on these three algorithms. From the simulation, we can see that the performance of the QRD-RLS and IQRD-RLS algorithms is better than RLS algorithm.
