CDMAFUNCTION

说明：  设计一个2FSK数字调制系统，要求： （1）设计出规定的数字通信系统的结构； （2）根据通信原理，设计出各个模块的参数（例如码速率，滤波器的截止 频率等）； （3）用Matlab或SystemView 实现该数字通信系统； （4）观察仿真并进行波形分析； （5）系统的性能评价。 (Design a digital modulation system 2FSK require: (1) design a digital communication system under the structure (2) According to the communication theory, design parameters of each module (such as code rate, filter cutoff frequency, etc.) (3 ) with Matlab or SystemView realize the digital communication system (4) observing the waveform simulation and analysis (5) system performance evaluation.)
