A Novel Method for Reducing Cross-Slot Interference between Base Stations in TD-SCDMA System
Wen Yuan Rao · Applied Mechanics and Materials · 2013
TD-SCDMA system can dynamically allocates time slots between uplink and downlink according to local service requirement, which causes cross-slot interference if adjacent cells have different direction links in the same slot. Because of the specialty of cross-slot interference between base stations, traditional methods which subtract interference in digital baseband don’t work well. A novel method is proposed. Simulation indicates that this scheme can effectively reduce the cross-slot interference.
