The file calculates and plots FM noise sidebands for a carrier. It also does sinusoidal modulation. This simple way of adding noise to a carrier is useful for simulation of PLLs. It turns out, though, that the mean of the randn function is not as close to zero as it could be, and this causes the fft to generate extra sideband energy, which makes it appear as if the noise is not what would be expected. This program gets around this by adding a fudge factor to the randn results to eliminate this problem. It took me ages to figure this out, I hope to reduce a similar effort for others

This paper represents the modeling and simulation of 2 MW Direct Drive PMSG Wind energy conversion system (WECS). The modelling of wind turbine and PMSG is carried out in simulink to determine its parameter. WECS consists different components namely Wind turbine, Generator, rectifier-inverter, controller system including transformer, grid etc. The PMSG and converter model are established in the d-q model. Keywords: PMSG, WECS, Wind turbine, rectifier, inverter, MATLAB/SIMLINK, transformer, Grid

pcm编解码模型，测试指定误码条件下PCM解码语音信号的音质和可懂度(pcm codec model, sound quality and intelligibility test conditions specified BER PCM decoded speech signal)

Robust image watermarking using two level discrete wavelet transform using constant scaling factor. At the same time you can use any optimization algorithm instead of constant scaling factor.

matlab source code for GMSK project

ntroduction to Stochastic Search and Optimization, 2003 This program runs a GA with real-number coding. Elitism is used and the mutation operator is simply the addition of a Gaussian random vector to the non-elite elements. The user is expected to set a variable expect_fn representing the expected number of function evaluations allowed.
