在多跳分组无线网中使用码分多址 (CDMA)技术可以明显地降低隐终端问题对网络造成的影响 .码分配是多跳无线网中使用CDMA的基本问题 .码分配的目的在于提高扩频码的空间重用、降低分组冲突以及反映网络的动态变化 .本文提出了一种多跳无线网扩频码分配算法 ,证明了其正确性并与其它算法比较了复杂度 .与以往的算法追求降低码的数目不同 ,本算法是假设扩频码的数目有一定的冗余 ,寻求算法的方便、快捷和低通信开销
The use of code division multiple access (CDMA) technology in multi-hop packet radio networks can significantly reduce the impact of hidden terminal problems on the network.Code allocation is the basic problem of using CDMA in multi-hop wireless networks.The purpose of code allocation is to improve Frequency reuse of the code to reduce packet collision and reflect the dynamic changes of the network.This paper presents a multi-hop wireless network spreading code allocation algorithm that proves its correctness and compared with other algorithms complexity.Compared with the previous algorithm pursuit Reduce the number of different codes, the algorithm is based on the assumption that the number of spreading codes have some redundancy, seeking the convenience of the algorithm, fast and low communication overhead
