Abstract
The bit error rate performance of a high chip rate, indoor code division multiple access multipath combining receiver with imperfections in power control, estimation of channel parameters (path amplitude and phase), and estimation of spreading code phase is analyzed. Imperfection in power control is taken into account by modeling the received signal power as a log normally distributed random variable. The estimate errors are modeled as zero mean Gaussian random variables. It is shown that the performance of such a receiver degrades when the variance of power control imperfection is above 0 dB, mean square error in channel parameter estimation is above 0.01, or standard deviation of the code phase error is above 0.1.
