摘要: |
从移动台和基站接收机输入端载干比以及T.S.Rappaport和L.B.Milstein提出的信道传输模型出发,对码分多址(CDMA)蜂房移动通信系统的上、下行链路带宽划分进行了分析,提出了非对称划分办法,同时给出了仿真结果。分析表明:上、下行链路带宽划分有效地提高了码分多址(CDMA)蜂房移动通信系统容量。 |

Abstract: |
Analyse the partition of bandwidth between uplink and downlink in CDMA cellar system on the basis of the inputting C/I of a receiver and the channel model presented by T. S. Rappaport and L. B. Milstein, and gives the method of the asymmetrical partition of bandwidth. The simulation results are also presented,showing that the frequency asymmetrical partition between uplink and downlink enhances the capacity of CDMA cellar system. |
Keywords: code division multiple access (CDMA) bandwidth partition mobile communication |
