说明：  经典无线链路预算模型，预测了在自由空间中由地形的非规则性造成的中值传输衰落。该模型适用于频段为20MHz至40GHz、路径长度为1km至2000km的情况。对于给定的传输路径，该计算机程序通过频率、路径长度、极化方向、天线高度、表面绕射率、地面有效半径和地面导电常数等参数可以确定传输损耗的大小。(Classic wireless link budget model, forecasts the in free space caused by terrain of regularity in the value decline.The model is suitable for the frequency of 20 MHZ to 40 GHZ, path length of 1 km to 2000 km.For a given transmission path, this a computer program can calculate the value of the transmission loss by frequency, path length, polarization direction, antenna height, surface diffraction, effective radius of the ground and ground conductivity constant parameters and so on.)

针对通信侦查课题，通过已知先验知识和截获信号，进行找出同步序列，匹配滤波，校正频偏和相偏，均衡，解交织，译码，恢复出原序列，最终得到的序列与原序列作对比得到误码率为0(Investigation subject for the communication, by known a priori knowledge and intercepted signal conducted to identify the synchronization sequence, the matched filter, correcting frequency offset, and phase deviations, balanced, deinterleaving, decoding, to recover the original sequence, the resulting sequence with the original sequence compared error rate is 0)
