为了提高MIMO-OFDM系统的数据传输率和频谱利用率,提出一种新的自适应算法。该算法在保证信道质量所需误码率和总发射功率的前提下,按照各个子载波衰落程度动态地分配比特和功率,使系统的总数据传输速率最大。理论分析得出,该算法降低了系统运算复杂度,能很大地改善系统的整体性能。(In order to improve data transmission rates and spectrum efficiency of MIMO-OFDM systems,this paper proposes a new adaptive algorithm. While the channel transmission quality to meet the requirements of a certain target BER(bit error rate) and total emissive power,according to each sub-carrier decline degree to adjust each sub-carrier modulation method freely,try to minimize the total data rate of system. Theory analysis shows the algorithm can reduce system complexity and improve overall performance of the ...)

说明： 基于Simulink的DPSK的通信系统仿真
Simulink 是MATLAB提供的实现动态系统建模和仿真的一个软件包，它让用户把精力从编程转向模型的构造，为用户省去了许多重复的代码编写工作；Simulink 的每个模块对用户而言都是透明的，用户只须知道模块的输入、输出以及模块的功能，而不必管模块内部是怎么实现的，于是留给用户的事情就是如何利用这些模块来建立模型以完成自己的仿真任务；至于Simulink 的各个模块在运行时是如何执行，时间是如何采样，事件是如何驱动等细节性问题，用户可以不去关心，正是由于Simulink 具有这些特点，所以它被广泛的应用在通信仿真中，利用Simulink 强大的工具箱和其建模的优势建立了常用的DPCM数字电话通信系统仿真模型，对该通信系统进行了模型构建、系统设计、仿真演示、结果显示以及综合性能分析，而且该分析方法同样可推广到其它的通信系统，具有普遍意义。(Simulink-based simulation of Simulink DPSK communication system is provided by MATLAB dynamic system modeling and simulation of a software package that allows users to shift attention from the programming model of the structure, the user save a lot of repetitive coding work Simulink Each module is transparent to the user, the user need only know the module s input, output and functional modules, rather than how the realization of the internal control module, and then left to the user to do is how to use these modules to build model to fulfill its a simulation tasks as Simulink s Ge Ge module at run time how Zhi Xing, Shi Jian yes how to sample, events are the details of how to drive and so on Xing problem, users can not care, Zheng Shi as Simulink those characteristics, so Ta is widely used in communication simulation, using Simulink toolbox and its powerful modeling advantage of the establishment of a common DPCM Digital telephone communication system simulation model, the communica)
