Abstract :
In this paper, we evaluate the performance of the receiver employing an iterative RLS-based data detection and channel estimation for the structured irregular LDPC coded MIMO-OFDM system. Using the EXIT chart analysis, the performance of the detector with various approximate decoding algorithms is analyzed
