摘要
在无线衰落信道自相关函数循环平稳突变特性分析基础上 ,本文提出一种基于预测插值的实时外推修正k步前向预测算法 ,在最小均方误差基础上推导了预测解析式 ,并进行了误差分析 .
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.
