OFDM比特加载、功率分配与信道估计算法仿真与建模-OFDM bit-loading, power allocation and channel estimation algorithm for simulation and modeling

OFDM modulation produces higher Peak Average Power Ratio (PAPR) whenever the carriers in OFDM symbol add synchronously in the time domain resulting in higher signal power. This high power saturates the power amplifier placed in the RF section res
