The use of low density parity check (LDPC) code in unitary space-time modulated orthogonal frequency division multiplexing (OFDM) system in broadband mobile channel was discussed. The proposed system can obtain space-time modulation without linear operation like space-time block code (STBC) and large coding gain using LDPC code. The effectiveness of the proposed system, was clarified, by evaluating bit error rate (BER) performance.
