摘要

研究了一种多径衰落环境下的直接序列CDMA功率控制机制。当对跟踪射线进行理想的功率控制时，最大的注意力集中在具有有限支路数量的RAKE接收器中的额外干扰上，即多径“范围”超过RAKE支路的数量。在假定多径瑞利衰落相对缓慢的情况下，导出了解析表达式，并给出了一个说明性的数值应用。

Additional interference in a RAKE receiver implementation of a CDMA power control mechanism

A direct sequence CDMA power control mechanism in a multipath fading environment is considered. The greatest attention is devoted to the additional interference in a RAKE receiver with a limited number of branches, i.e. the multipath "range" exceeds the number of branches of the RAKE, when an ideal power control on the tracked rays is assumed. Analytical expressions are derived under the assumption of relatively slow multipath Rayleigh fading and an illustrative numerical application is then given.<>
