进行EFEC(增强型FEC)的研制,主要应用于时延要求不严编码增益特别高的光通信系统。
Study on EFEC is mainly applied to the optical communication which time delay is not requested strictly and the coding plus should be very high.
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。
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.
利用该方法良好的收敛性,可以借助于电子计算机快速的构造目前已知的具有最大码率和最小解码时延的多天线复正交空时分组编码矩阵。
By the convergence of the method, we can fast construct a COSTBC matrix with the maximal rates and the minimal decoding delays that we all know now recur to the computer.
