查询词典 base station

To overcome the above described drawbacks,P.W.Baier and other researchers propose a novel multi-user transmission scheme for the downlink of TD-CDMA termed joint transmission. This paper discusses the application of JT technology in the FDD system,and proposes a new solution: Through feedback signal,channel pre-estimation is accomplished at the base station.

为此提出了名为联合传输的多用户传输方式，可以利用TDD模式上下行链路移动无线信道脉冲响应相等的优点，只在上行链路对信道进行估计，下行链路利用估计得到的信道冲击响应值，把在移动台判决传输信号的任务交给基站来完成，利用这种技术可以提高系统性能和减少系统复杂性。1系统模型及JT原理联合传输技术[1～3]，可由信道传输概念引出，如图1所示。

A method for broadcasting channel information, available channel and data rate of a base station in a CDMA communication system.
