摘要多输入多输出技术被预期是在第三代通讯系统长程发展下用于下链进阶通用无线接取中一个非常重要的构成要素之一。 - This thesis is divided into two parts . in the first chapter , the existence of markov chains in random environments is described , and their properties are studied . the concepts of recurrence , transience , - irriducibility and strongly - irriducibility are introduced . the sufficient and necessary condition for recurrence of strongly - irriducible markov chains in random environments is obtained , then some sufficient conditions for recurrence and transiece of markov chains in random environments are given . in the second chapter , some results on the existence of invariant measure of bichains ( xn , tn ) are outlined
全文共分两章，在第一章中，简述了随机环境中马氏链的存在性及其一些性质，介绍了常返性，瞬时性， -不可约，强-不可约等概念，并且得到了具有强-不可约性链常返性判定的充分必要条件，以及在一般情形下链(
