Abstract

Based on the analysis about cyclostationary inflection from the autocorrelation of samples in radio fading channel

a modified real-time K-step channel fading predicting algorithm is proposed.Mathematic derivation

and also error analysis

are finished based on MMSE criteria.Simulating results show that the proposed algorithm with power-control-loop can reduce the prediction error and obtain BER improvement in wireless Jakes channel.
