Research On Packet Scheduling For TD-SCDMA Hsdpa

HSDPA (HighSpeed Downlink Package Access) is a research hotspot of the3rd Mobile Telecommunication Technology. Aimed with smart antenna, joint detection and dynamic resource allocation, TD-SCDMA system makes the HSDPA better application. As a key role of HSDPA technology, the fast Packet Scheduling Algorithm decides the packet transmission performance of system and affects capacity and efficiency.The thesis makes a deep study for the fast Packet Scheduling Algorithm of HSDPA in TD-SCDMA system. After the introduction of3G packet data traffic and the analysis of the classic fast Packet Scheduling Algorithm, the author summarizes the design module for HSDPA Packet Scheduling Algorithm and puts forward a new compositive scheduling algorithm. With the analyses of the emulation results and the comparison with classic algorithms, it proves the validity of the new algorithm.
