Abstract
The method of LDPC coded rotational modulation in OFDM systems is presented in this paper. This method obtains more coding gain modulation compared to traditional coded modulation techniques in fading channels. The results of simulation show that coded modulation gain of rotation modulation is more apparent than that of non-rotation modulation, and it is more apparent with high bit-rate. In addition, the optimal angle of rotation modulation is given.
