Abstract :
A unitary space-time modulated orthogonal frequency division multiplexing (OFDM) system using low density parity check (LDPC) code for increasing the system performance is proposed. The proposed system can obtain space-time diversity using unitary space-time modulation without linear operation like space-time block code (STBC), and large coding gain using LDPC code.
