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))

把地理区域分成一个个小区,蜂窝系统在该区域内提供无线覆盖。把可用的频谱分成很多信道,每个小区分配一组信道。使用频分双工(FDD)。在小区间进行频率利用,N个小区构成一个簇,簇间进行频率复用。定义了传播特性(信道参数)以及同频小区的位置。信道的参数包括:小区半径,路径损耗指数,以分贝为单位的对数正态阴影的标准差,基站发射功率级,移动台发射功率级,每个小区的扇区数,扇区化天线的正反向比,要仿真的瞬时位置的组数,同频干扰阈值。(To a geographical area is divided into small areas, cellular systems in the region to provide wireless coverage. The available spectrum is divided into multi-channel, each plot the distribution of a group of channels. The use of frequency division duplex (FDD). In the district between the frequency of use, N plots constitute a cluster, cluster between frequency reuse. The definition of the propagation characteristics (channel parameters), as well as with the frequency of residential location. Channel parameters include: cell radius, path loss index to decibels for units Lognormal shadow of the standard deviation, the base station transmitter power level, mobile station transmitting power level, the number of sectors in each district, sector of the antenna the pros and cons to the ratio, to the transient simulation of the group a few positions, the same frequency interference threshold.)
