Optimal performance of convolution coded OFDM

摘要

OFDM is the next generation transmission technique for high bit-rate communication systems. OFDM has suffered by peak-to-average power ratio (PAPR), it is one of the major disadvantages of OFDM. In this paper, Convolution code is applied to minimize the peak-to-average power ratio (PAPR) and BER of Orthogonal Frequency Division Multiplexing (OFDM) system, and had investigated effect of convolution code on PAPR and BER. We also proposed method to find optimal values of Eb/No for minimum PAPR and BER based on the tradeoff between the number of assigned subcarriers, order of modulation and coding rate. Simulation result shows that the proposed method had effectively obtained the minimum PAPR and BER with convolution code at optimal value of Eb/No for MIMO OFDM channel.
