代码说明:

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.)

    A dynamic estimation of channel is necessary before the transmission of the signals since the wireless channel is time–varying..we use MMSE method for channel estimation. The MMSE method calculates the following, MMSE channel estimator is designed to minimize the estimation MSE. The MMSE estimate the channel responses.
