1. it is based on the mean square error ( mse ) principle and we prove the validity of the method by computer simulations . to make a thorough understanding of mimo adaptive equalization system, in this thesis the author : 1 ) ananlyze the characteristics of mimo wideband channels and the modeling and simulation of 3gpp scm; 2 ) research the capability of mimo linear adaptive equalization and mimo non-linear adaptive equalization by computer simulations; 3 ) present a new method for selecting the order of adfe model 4 ) implement the adfe on adsp-21160 for static image transmission, and already achieve satisfactory experimental result, which make a foundation for mimo adaptive equalization to be appllied in the real communication systems
   为对mimo自适应均衡系统性能和设计做更深入的理解和研究,本文主要:1)研究了宽带选择衰落信道特性及3gppscm信道建模仿真;2)mimo线性自适应均衡器和mimo非线性自适应均衡器系统的性能分析和仿真实现;3)mimo系统下的判决反馈均衡器的阶数选择仿真试验分析;4)把mimo自适应判决反馈均衡运用到了硬件仿真平台上,采用了基于adsp-21160的硬件dsp开发板,对静止图片的传输进行了试验、分析和比较,得到了较满意的实验结果,使mimo自适应均衡在实际通信系统上的应用及实现奠定了现实基础。
2. the computational complexitity of inverse qr-rls algorithm and square-root kalman algorithm which had numerical stability were analysized . because the qr-rls needed the squart-root and inverse of matirx operation, which had large computation, was not fit for fixed-point dsp implement of real time, adfe based on square-root kalman algorithm was applied to fixed-point dsp algorithm implement of the equalizer of hf channel
   对采用数值稳定的逆qr-rls算法和平方根kalman算法的计算复杂度进行分析，逆qr-rls算法需要平方根和求逆运算，计算量大，不适于定点dsp的实时实现，故采用平方根kalman算法的adfe作为短波信道的定点dsp算法实现方案。
