代码说明:

调近似表示空间的概念,指出了各种不同的信息系统均可以转化为协调近似表示空间.同时,在协调近似表示空间上,给出了属性协调集的判定定理以及属性约简方法,给出了三类不同属性(核心、相对必要属性、不必要属性)的特征定理.

    衡量一个数字通信系统性能好坏的指标很多,误码率性能就是一个重要的指标。误码率是指错误接收的码元数载传输总码元数中所占的比例。在该章中,我们将通过MATLAB仿真在发送平均功率和传输速率相同的情况下(A digital communication system performance measure indicators of good or bad a lot of bit error rate performance is an important indicator. Bit error rate refers to the number of errors contained in received transmission symbol the number of total yards per share. In this chapter, we will send through MATLAB simulation of average power and transmission rate in the same circumstances)
