摘要: An original data signal is transmitted by a predetermined transmission power, the distorted during received, and received output after being restored to signal, SNR for each subchannel calculated higher power allocated having lower SNR. If of exceeds maximum limit, limit redetermined as subchannels whose limit. Then, negative determined if does not exceed or above redetermination step completed. Thereafter, controlled power. As result, efficiency increased near value, thereby prevent loss.
