Interference Reduction in Overlaid WCDMA and TDMA Systems

In this paper, the performance of WCDMA uplink system for UMTS mobile communications is evaluated. Also, the possibility of increasing mobile communication cell capacity through merging WCDMA and TDMA systems in one cell is investigated. An interference canceller is proposed to reduce, or even completely cancel, the interference between WCDMA and TDMA, hence enabling them to work together. This results in a considerable increase in the cell capacity. The coexistence of WCDMA and TDMA systems in one cell is proven to be possible via computer simulations.
