本试验是用数字基带处理方法来实现调试期算法的基带硬件实验。 通过用软件matlab进行了GMSK相位路径和眼图的仿真,之后对任何一种五位随机码，每周期八次的任一抽样时刻，和任一相位区域(0、1、2、3)的任一组合，计算出相位 ，并对 以及 进行1024位的量化、编码成10位二进制码表。进一步利用matlab从上述的码表得出GMSK基带波形的眼图，和理论上计算的眼图比较，一致性很好。(眼图主程序) (This test is a method to realize the digital baseband processor debugging phase algorithms with hardware-based experiments. By using the software matlab a GMSK phase path and the eye diagram of the simulation, after any one of five random code, eight times per cycle of any one sampling time, and any one-phase region (0,1,2,3) of any combination of one to calculate the phase, and 1024 as well as quantitative, encoded into a binary code table 10. Further use of matlab code from the above tables GMSK baseband waveform eye diagram and eye diagram theoretically compared to a good consistency. (Eye diagram of main program))
