Nonlinear prediction of frequency-domain channel parameters for channel prediction in fading and fast Doppler-shift change environment

摘要

Performance of mobile communications often suffers from various fading phenomena. To reduce the adverse effect, we may employ such techniques as diversity reception and error-correcting code. Another countermeasure is channel prediction [1] with which we predict the channel change in time to realize pre-equalization such as transmission power control or adaptive modulation. It leads also to high-capacity spatial-domain multiple access (HC-SDMA) [2].
