| 摘 要： | 证明了利用现有的CDMA基本原理无法实现1x EV-DV应该给多个用户同时提供高速数据和语音业务的应用要求.给出一种可行的利用码分多址(CDMA)和时分多址(TDMA)实现cdma2000 1x和1x EV-DO同频点兼容的方法.使用该方法可成10倍提高小区内的下行信道频谱利用率,而且只需使用最易实现的干扰抵消器,大幅提升900 MHz优质稀缺车载移动通信频段的频谱利用率.

| Abstract: | It is proved that 1x EV-DV's requirement of simultaneous providing high rate data and voice services for multiple users cannot be met based on the current CDMA fundementals.A feasible CDMA and TDMA intgrated scheme is proposed to support cdma2000 1x and 1x EV-DO compatibly working on common frequency point.The scheme can increase the spectrum utilization efficiency of down link within the cell by 10 times.It uses the easiest-to-implement inteference eliminator and will significatly enhance the spectrum utilization efficiency of 900 MHz frequency band which is optimal but scarce for vehicular mobile communication. |
