This technique uses different time delay values of the LFM pulse to code the transmitted information, and uses time delay estimation technique to perform decoding.
该技术利用线性调频信号（LFM）矩形脉冲的时延值进行时延编码，在接收端采用时延估计技术进行时延解码。
The corresponding simulation and analysis shows that the new criterion does help reduce the average number of decoding iteration and the time delay while the BER performance is almost not degraded.
经仿真验证，该准则在译码性能几乎没有下降的同时，有效的减少了平均迭代次数，降低了时延。
