在微蜂窝码分多址小区的上行链路实现比特同步的设想
THE BIT-SYNCHRONOUS COMMUNICATION ON THE UP-LINK OF MICRO-CELL CDMA SYSTEMS
-
摘要: 本文认为在微蜂窝小区的结构下,即蜂窝小区的半径在100m到200m时,可由小区基站发出比特同步信息,小区内的各手持机根据接收到的比特同步信息,实现上行链路的比特同步通信。本文的分析和计算表明,同步通信可显著地降低误码率。

Abstract: This paper points out that in micro-cell situation, that is the cell s radius is between 100m and 200m, the cell s basestation can transmit the bit-synchronous information, and all the mobile phones of the cell can be bit-synchronous on the up-link according to this information. The analysis and calculation present that bit-synchronous can greatly decrease the bit-error probability. -
