  • hmm-1.03.rar This code implements in C++ a basic left-right hidden Markov model and corresponding Baum-Welch (ML) training algorithm. It is meant as an example of the HMM algorithms described by L.Rabiner (1) and others.
  • bpsk.rar 层空时码有三种普遍的检测算法:最大似然(Maximum Likelihood ,ML)检测算法、迫零(zero forcing ,ZF)检测算法、最小均方误差(Minimum Mean Squared Error,MMSE)检测算法。
  • basic_iterative.zip This is a matlab program using the most-likelihood method to estimate the frequency of a sinusoid wave. Also, a basic filter is provided to check the benefit from using that. The result show that ML method reacches CRB at normal SNR.
  • basic_ESPRIT.zip This is a matlab program using ESPRIT method the estimate the frequency of a sinusoid wave. It is shown that this method finds out exactly the fact when there is no noise, but works worse than ML in accuracy in noise.

  • CMMB.rar 为了减少无线信道中存在的多径和频偏对中国移动多媒体广播(CMMB)系统传输信号同步的影响,本文结合CMMB标准协议规定的具体帧结构,分析了符号同步对系统的影响,讨论了传统最大似然(ML)算法的优缺点,并基于文献中的无数据辅助算法,提出了一种适合该系统并且复杂度较低的粗符号定时同步算法。仿真结果表明,在AWGN及多径信道环境下,新算法可以有效克服传统算法相关峰不明显的缺陷,其估计性能更好
