| 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,a re finished based on MMSE criteria.Simulating results show that the proposed alg o rithm with power-control-loop can reduce the prediction error and obtain BER i mprovement in wireless Jakes channel. |

| Keywords: | second-order statistic cyclostationary long-term channel predicting cyclostati onary area |
