Most of these phones are HSPA enabled as operators move to more efficient 3G+ networks, fulfilling demand among users for faster and less expensive uplinks and downlinks for social networking, multimedia messaging, Location Based Services and other new services.

这些话机中绝大部分具备 HSPA 功能，这是因为运营商逐渐改用效率更高的 3G+网络，满足用户对于社交网络、多媒体通信、定位服务以及其他全新服务所需的更快、更廉价的上行链路与下行链路需求。

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.
