Abstract :
This paper investigates the channel access algorithms with measurement error. Two kinds of channel access algorithms in the CDMA network, SIR based (CPICH RSCP/ISCP) and Ec/Io based (CPICH RSCP/RSSI) channel access algorithms, were analyzed in our work. Comparisons were carried out between the two kinds of channel access algorithms. Simulations were done and the capacity loss due to the measurement error is given. All the simulations were done in the TDD/CDMA system level simulation platform
