Open in MATLAB Online To elaborate on Honglei's answer. If the signal you are trying to design a matched filter for, is x, then -- >> b = x(end-1:1); >> y = filter(b,1,x); You should already have x. 1 Comment mmm sssson 9 Jan 2012 ...
MATLAB Simulation for Matched Filtermatch filter in matlab
Copy Code Copy Command Apply a matched filter, using a Hamming window to do spectrum weighting. Get waveform = phased.LinearFMWaveform('PulseWidth',1e-4,'PRF',5e3); x = waveform(); mfilter = phased.MatchedFilter( ... 'Coefficients',getMatchedFilter(waveform), ... 'SpectrumWindow','...
You are mixing several things here. y in your script is a signal vector, not a waveform, so it does not work with the step() method.
matlab匹配滤波代码在MATLAB中使用匹配滤波器的最佳二进制脉冲接收器 设计了一种最佳接收器,用于接收添加了噪声的极性二进制极性编码信号。 对二进制极性编码信号使用了匹配的滤波和阈值检测。 计算接收到的序列的CRC-8。 对接收到的二进制序列的一阶扩展执行霍夫曼编码。
USING MATCHED FILTER” 1. INTRODUCTION A matched filter is a technique to detect the presence/parameters of a known signal in additive noise. A template of the known signal is correlated with the noisy signal to determine the presence of the known signal. Since correlation is a convolution oper...
MATLAB Online에서 열기 Hi Muhammad, I understand that you want to plot “matched filter output versus the range of the radar”. The “matched filter” can be implemented in various ways. In the code provided by you, a “matched_filter” function is used. This is not an in...
