说明：  跳频是按跳频序列随机改变一个信道所占有频道频率的技术。在GSM 系统中，可利用跳频技术频率分极和干扰分极的特点，改善网络质量。引入跳频技术，可保证在网络软拥塞不上升的情况下，频率复用度较小。(FH frequency hopping sequence is based on a random channel change in the country channel frequency technology. In the GSM system, can make use of frequency hopping technology sub-polar and polar characteristics of interference and improve network quality. The introduction of frequency-hopping technology to ensure that congestion in the network does not increase in the soft case, a smaller frequency reuse moment.)

Useing the MATLAB command remez to obtain a low pass filter z(n) with a cutof frequency of 40 Hz at a sample rate of 1000 Hz.
