Turbo_code_simulation
1. 程序中Turbo译码采用了MAP,LOG-MAP,和MAX-LOG-MAP三种算法。
2. 以xxx开头的四个mat文件是四种给定的Turbo码在译码时用到的参数,保存下来的目的是
加快仿真的速度,如果你所仿真的Turbo码不是程序中列出的任意一种,你可以通过函数
trellis来生成自己的相关参数。
3. 程序支持1/2和1/3两种码率的Turbo码,其中1/2码率的Turbo码通过矩阵[1 0 0 1]打
孔得到。在译码时通过对打孔位置添0恢复成1/3码率的码字。
4. 程序中的信噪比表示Eb/N0,通过此参数求得N0,对发送信号进行加噪。(1 program in Turbo decoding using the MAP, the LOG-MAP, and three kinds of the MAX-LOG-MAP algorithm.)

impacting-filter
雷达通信一体化系统,针对非波动目标以及波动目标的雷达探测性能分析。(he dual-frequency MPPSK-MODEM platform is a flexible one. When ranging accuracy request is low or platform is particularly affected by power limitations, the platform would perform both data transmission and range measurement with single frequency modes. In this paper, the ranging resolution of MPPSK pulse waveforms with the match filter and impacting filter processing method are discussed, respectively. Also, the selection of MPPSK modulation parameters for ranging is considered. In particular, requirements that allow for employing such special parameter values for range measurements with high accuracy and high range are investigated. Moreover, high repetition frequency (HRF) bi-phase code MPPSK pulse train base on m sequence are presented, the ranging accuracy of the proposed signal with the match filter processing method is deduced. In addition to theoretical considerations, the paper presents system simulations and measurement results of single-frequency MPPSK intergated systems, d)
