MIMO-OFDM系统中的自适应算法中的一种。Chow算法是根据各个子信道的信道容量来分配比特的。与Hughes-Hartogs算法相比，没有了大量的搜素和排序，简化了算法复杂度。(MIMO- OFDM systems in one of the adaptive algorithm. Chow algorithm is based on the channel capacity of each channel to allocate bits. Compared with Hughes- Hartogs algorithm, not a lot of search and sorting, simplify the algorithm complexity.)

这是研究欧洲DVB-T标准的一套合集，主要介绍了DVB-T单频网的同步技术，以及系统设计和实现。其中对DVB-T单频网进行了详细的讲解，对研究我国的数字电视广播技术也有很好的借鉴作用。(This is the study of the European DVB-T standard a collection, mainly introduces the synchronization technology of DVB-T single frequency network, and the system design and implementation. It make a detailed explanation of DVB-T single frequency network, also have a very good reference for digital television broadcast technology research in china.)

说明：  ：载波频率偏移是OFDM系统实现的关键问题之一。分析了OFDM 系统载频偏移估计的2 种算法，即利用循环前缀和训练序列方法。它们均为最大似然估计方法。分别讨论了它们的基本 思想、实现方法和仿真结果。可以看出基于循环前缀算法复杂度较小，精度不高，而基于训练序列 的算法有较高的估计精度，但降纸了系统传输效率。(Abstract：Carrier frequency ofset is one of the key problems in OFDM system．Two foundational methods 。cycling prefix—based and training sequence—based algorithms。to estimate OFDM carriers~equency ofset are analyzed．Then it discusses their basic thoughts。implementing methods and simulation resuits． Finally。merits and demerits of every algorithm are supposed．It concludes that the cycling prefix— based algorithm has less complexity and less precision。and that the training sequence—based algorithm has better estimation performance at the cost of transmission efficiency．)
