During the BPSE process, a high-speed special mode frame is sent, bit error rate (BER) is fed back to the sender, as well as signal to noise (SNR) and BERs for each rate are obtained by looking up the empirical BER/SNR curve.

- 其中，BPSE先通過(guò)發(fā)送高速特征序列串來(lái)測量比特誤碼率(Bit ErrorRate)，然后根據BER/SNR(Signal to Noise Ratio)經(jīng)驗曲線(xiàn)，查表得出當前信道的SNR以及當前SNR下各個(gè)速率的BER。
