Abstract

The cochannel interference for a code division multiple access (CDMA) wireless communication network is considered and analyzed. A new CDMA cellular network architecture has been proposed. An analytic expression for the proposed method is derived. Simulation results show that the proposed method provides better signal-to-noise (S/N) ratio than the existing cochannel interference reduction methods. In the proposed microzoning architecture, a significant reduction of cochannel interference is achieved compared to sectoring and omni-directional architectures.
