代码说明:

  正交匹配追踪(OMP)在稀疏分解与压缩感知重构,稀疏分解先于压缩感知提出,信号稀疏表示的目的就是在给定的超完备字典中用尽可能少的原子来表示信号,可以获得信号更为简洁的表示方式,从而使我们更容易地获取信号中所蕴含的信息,更方便进一步对信号进行加工处理,如压缩、编码等。(Orthogonal Matching Pursuit (OMP) is used in sparse decomposition and compressive sensing reconstruction. Sparse decomposition is proposed prior to compressed sensing. The purpose of signal sparse representation is to represent the signal with as few atoms as possible in a given overcomplete dictionary. The more concise representation of the signal allows us to more easily obtain the information contained in the signal, making it easier to further process the signal, such as compression and coding.)

  • IterativeClosestPointMethod
    ICP fit points in data to the points in model. Fit with respect to minimize the sum of square errors with the closest model points and data points. Ordinary usage: [R, T] = icp(model,data) INPUT: model - matrix with model points, data - matrix with data points, OUTPUT: R - rotation matrix and T - translation vector accordingly so newdata = R*data + T . newdata are transformed data points to fit model see help icp for more information (ICP fit points in data to the points in model.

    1、根据干扰总功率要求,在PSK调制信号带宽内产生单音干扰和多音干扰信号,并叠加到产生的信号源上。 2、将收到干扰的信号进行频率搬移到基带,然后通过匹配滤波器以及解调过程得到信息,统计误码率并与真实信息的解调误码率进行对比,评估音频干扰对PSK信号的干扰效果。 (1, according to the total power requirement of interference generated tone signal interference and multi-tone interference in the PSK modulated signal bandwidth, and superimposed on the signal generated by the source. 2, the received interference signal to a baseband frequency shift, and the information obtained by the matched filter and a demodulation process, statistical error rate BER and the true information demodulation comparison, evaluation of the PSK signal, audio interference interference effects.)
