| 摘 要： | 在分析卡尔曼算法收敛性能基础上，提出了组合卡尔曼均衡算法，并在时变信道上以线性均衡器（ＬＥ）及判决反馈均衡器（ＤＦＥ）研究了其性能。组合卡尔曼算法与Ｋａｌｍａｎ算法收敛速度相同，稳态误差相近，但克服了Ｋａｌｍａｎ算法因计算误差阵ＰＫ产生会入误差累积而使算法发散的缺陷．

| Abstract: | According to analysing the convergence characteristic of Kalman algorithms, a new equalization algorithms of composite Kalman is proposed, and its pesformance is investigated by simulating LE and DFE equalization structure over timevaring channel. The new algorithms has the same convergance speed and steady state error as the Kalman algorithms, but overcomes the instability of Kalman algorithms because of the accumulation of error produced from the rounding error of computing error matrix Pk. |
