In this simulink model , QPSK modulation and demodulation is simulated .A square root raised cosine pulse shaped signal is modulated and given as input to the demodulator.The received signal is demodulated and given to the detector where it is matched filtered and down-sampled .The effects of symbol timing offset can be seen by varying the phase of down-sampling operation.The signal transmitted is recovered at the detector output.

PSO algorithm matlab code

We propose a generalized equation to represent a continuum of surface reconstruction solutions of a given non-integrable gradient field. We show that common approaches such as Poisson solver and Frankot-Chellappa algorithm are special cases of this generalized equation.

HHT谱计算程序，不是rilling版本，用改进的Hilbert变换，效果好一些，供大家参考。(HHT spectrum of the calculation procedures, rilling is not a version of the Hilbert transform used to improve the results better for your reference.)
