This is a superheterodyne reciever simulation, created in MATLAB - Simulink. The purpose is to study the effect of perturbations on the imaginary frequence and on the intermmediate frequence, in the context of incoherent demodulation.(This is a superheterodyne reciever simulation, created in MATLAB- Simulink.

Levenberg-Marquardt 算法的 Matlab 实现，附例子代码(Levenberg-Marquardt Algorithm implement in Matlab. )

Basic function to locate and measure the positive peaks in a noisy data sets. Detects peaks by looking for downward zero-crossings in the smoothed third derivative that exceed SlopeThreshold and peak amplitudes that exceed AmpThreshold. Determines, position, height, and approximate width of each peak by least-squares curve-fitting the log of top part of the peak with a parabola.
