Research towards meeting the higher demands for higher data rates was the main reason for the birth of an evolution technology towards the 4th generation mobile communication systems. This evolution to the current 3rd generation UMTS systems

Single path or multipath Rayleigh fading channel simulation, This function is used to calculate the arbitrary function of the first order partial derivative (numerical methods), Bottom-pass and band-pass FIR and IIR filter bottom pass and band-pass f

Single path or multipath Rayleigh fading channel simulation, Target can be extracted in a picture you want, Can be widely used in data analysis and forecast data.
