A larger error often occurs in measured results by multi-specimen J-R curve method because of the difficulty in determining the blunting line equation.

During the BPSE process, a high-speed special mode frame is sent, bit error rate is fed back to the sender, as well as signal to noise and BERs for each rate are obtained by looking up the empirical BER/SNR curve. During the SLRA process, the equation of goodput relative to BER and frame length is solved, to obtain the maximized goodput and its related BER and frame length.

SLRA先通过求解有效带宽、BER和包长度的解析方程，然后得到各种速率下的最优有效带宽、及其相应的包长度，从而在理论上优化有效带宽；由于SLRA计算过程非常复杂，我们提出了近似查表的方法来简化优化过程，使得其适用于便携式通信设备。
