| Abstract(in English) | We propose an OFDM system with trellis coded nonuniform PSK modulation. In the proposed system, an alternative partial transmission sequence (PTS) scheme is used, in which subcarriers of OFDM are divided into several clusters and an adaptive nonuniform PSK signaling is implemented in each cluster to minimize the peak power. We also apply trellis coded modulation (TCM) to the nonuniform signaling system to avoid the degradation of average bit error probability caused by the signal nonuniformity. With and without TCM scheme, the proposed system is compared with the conventional system. We evaluate both the PAPR (Peak to Average Power Ratio) performance and the bit error probability performance under AWGN environment using computer simulation. |
