METHOD FOR WIRELESS FADING CHANNEL SIMULATION IN WIRELESSS COMMUNICATION SYSTEM AND RECORD MEDIA RECORED PROGRAM FOR REALIZING THE SAME

摘要

A method for fading channel simulation in a wireless communication system and a recording medium storing a program for realizing the same are provided to improve performance by dividing Doppler coefficients, inputted into a simulation system, into two groups or optimizing each Doppler coefficient, so that autocorrelation can be close to that of a reference model in comparison with an existing JM(Jakes Method) model. In a method for fading channel simulation in a wireless communication system to minimize MSE(Mean Square Error) from a reference model, Doppler coefficients are divided into two groups. Weights are given to signals which are generated in sinusoidal signal generators having differential phases. A weight variable within a range(1~N-1) differs from a weight variable at Nrd(N is the number of delivery paths). The weight variable within the range(1~N-1) is alpha and the weight variable at Nrd is beta, wherein alpha=0, beta=0.
