【摘要】 高速分组数据(HRPD)技术能够很好地支持移动通信网络中各种类型数据分组应用,采用干扰消除技术能够有效提高系统的容量和对各用户信号正确接收。基于基站协调器的协作式迭代并行小区间干扰消除算法利用基站协调器监视相邻小区的强干扰用户,并且通过信令传递强干扰用户的特征信息,利用基站协调器的协作来实现迭代式的并行小区间干扰消除。仿真结果表明,该算法可以有效的消除邻近小区对本小区的干扰,与不使用小区间干扰消除技术相比较,其性能有所提高。更多还原

【Abstract】 All kinds of packet services can be supported by High Rate Packet Data (HRPD) technique very well in mobile telecommunications system, and the capacity of the system can be improved efficiently as each user receives its data correctly when the interference cancellation algorithm is used in target system. Iterative parallel inter-cell interference cancellation algorithm based on base station cooperation uses a coordinator to monitor the stronger interference user in adjacent cell and transmit its signature information through signal, i.e. it is implemented between base station and coordinator. The simulation is conducted and its result shows that the new inter-cell interference cancellation algorithm has a better performance in eliminating interference from vicinity.更多还原
