Abstract :
To investigate the application of spread spectrum code division multiple access (CDMA) technology to the future Personal Communications Services (PCS), a comprehensive study of CDMA PCS in the 1.8 GHz band in various radio environments has been conducted by Telesis Technologies Laboratory (TTL) in cooperation with Qualcomm Inc. in San Diego. This paper presents simulation results on CDMA PCS system performance. In this simulation, we consider interference in the reverse link introduced by users within the center cell as well as users in the first two rings of neighboring cells. Frequency reuse efficiency is simulated under various propagation conditions. The system capacity is assessed for uniform and non-uniform cell loading. The effects of imperfect power control on system capacity is also discussed
