A predictive power control algorithm for the uplink transmission in wideband code division multiple access ( WCDMA ) systems is presented. 针对宽带码分多址(WCDMA)系统的上行链路,提出了一种基于干扰预测的功率控制方法。
Between them, the four companies own the majority of the essential intellectual property rights relating to W-CDMA ( wideband code division multiple access ) technology. 在这两种技术之间,这四家公司拥有W-CDMA技术的大部分核心知识产权(宽带码分多址(WCDMA))。
Several space-time coding based transmit diversity techniques for wideband code division multiple access ( WCDMA ) systems with four transmitter antennas are investigated. Performances of the rake receivers are analyzed and compared with those of the multi-antenna receive diversity techniques. 研究了WCDMA系统4发送天线时可能存在的几种空时编码发送分集技术,给出了各自的rake接收模型并研究了在衰落信道中的接收性能,同时也与多天线的接收分集技术做了比较。
