此程序主要演示通道间幅度误差对DBF旁瓣电平的影响。(This program is mainly to demonstrate of effect of channel amplitude errors on the sidelobes of DBF.)

与已有的代码相比，本代码不仅包含调制解调、星座图、误码率等已有功能，更添加蒙特卡洛仿真，具有更好的性能，程序会产生一些图，能看清楚调制解调的过程中一步一步的编解码过程。(Compared with the existing code, the code contains not only the modulation and demodulation, constellation diagram, such as bit error rate for existing function, more add a Monte Carlo simulation, has better performance, the program will produce some map, can see the encoding and decoding process step by step in the process of modulation and demodulation..)

eye pattern, also known as an eye diagram, is an oscilloscope display in which a digital data signal from a receiver is repetitively sampled and applied to the vertical input, while the data rate is used to trigger the horizontal sweep. It is so called because, for several types of coding, the pattern looks like a series of eyes between a pair of rails. It is an experimental tool for the evaluation of the combined effects of channel noise and intersymbol interference on the performance of a baseband pulse-transmission system. It is the synchronised superposition of all possible realisations of the signal of interest viewed within a particular signalling interval.
