摘要
提出了一种跳频序列的设计方法,将其应用于构建多子网的通信系统可以有效降低子网间的相互干扰。该方法在序列设计中引入了子网间用户的空间分布特性,在序列构造中充分利用了传播时延和传播衰减来降低序列间的频点干扰。理论推导表明,该方法设计的跳频序列可以显著降低子网间跳频序列的有效碰撞,在相同的频带利用率下比频分组网方式有更强的抗干扰能力。
A design of frequency hopping(FH) sequences for multi-network communication systems is proposed to decrease the interference among the multi-network. The distribution of multi-network is considered in se- quence design, which reduces the conflict of frequency hopping sequences by using the delay and attenuation of the different transmitting signals. The theoretical analysis indicates that there is an obvious drop of the carry fre- quency conflicts among multi-network, and the communication system has better anti-jamming performance compared with that of FDMA(Frequency Dividing Multiple Access) system.
