A cell planning scheme for WCDMA systems using genetic algorithm and performance simulation platform

This work presents a cell planning scheme using the genetic algorithm with the help of the propagation model and digitized building information to achieve the acceptable solutions based on impact of background noise for the WCDMA systems. Among these solutions, the best one is selected by a performance simulation platform with a RAKE receiver, which evaluates the BER performance with delay profiles obtained from ray-tracing simulator. The required coverage and maximum throughput can be achieved with the optimum solution for base station number, locations, antennas heights, and transmitting power. Thus, an easy and efficient cell planning for WCDMA systems in the initial stage of system development could be delivered.
