由于前导码在发送信号中是反复发送的，所以降低前导码的峰均比值对整个发送信号有较大影响。发送信号的数据位和校验位不能做降峰均比操作，否则会影响系统的误码率和稳定性-As the preamble is repeatedly sending a signal to send, so reducing the peak to average ratio preamble to send signals to the entire greater impact. Send signal data bits and parity bit can not do PAPR reduction operations will affect the bit error rate and the stability of the
