Abstract :
In a switched-beam smart antenna system, predicting the message signal during the interval of signal fading or beam changing is required. In this paper, a channel prediction algorithm that is capable of estimating a future block of fading coefficients is studied. Jakes channel model is used to represent the wireless communication channel. It is shown that the algorithm is able to predict the fading coefficients quite well. The effects of observation interval length, number of scatterer signals in the channel model and the Doppler frequency on the estimation algorithm are investigated.
