- 論文の詳細を見る
This letter investigates the peak-to-average power ratio (PAR) reduction scheme employing a simple symbol transform in OFDM-CDMA systems. This approach is very simple because of no additional complexity and works with arbitrary numbers of subcarriers and without restriction on the allocation of spreading code, maintaining an original transmission efficiency. Simulation results show that the investigated scheme gives the PAR reduction gain of 2-3 dB compared to the original OFDM and OFDM-CDMA signals, and can provide the further PAR reduction by combing the partial transmit sequence (PTS) scheme, which is less complex compared to the ordinary PTS approach.
