METHOD AND CORRESPONDING RECEIVER FOR ESTIMATING CELL GEOMETRY IN A SYNCHRONOUS CDMA COMMUNICATION SYSTEM

摘要

A method and corresponding receiver for processing signals received over a wireless communication channel by a receiver in a wireless cellular network. The method comprises: receiving a sequence of signal samples; using the received sequence of samples to estimate at least one channel coefficient for at least one transmission path of the signal; generating an estimate of an orthogonality factor (ß) based on the at least one channel coefficient; generating an estimate of the disturbance (s i 2) on the at least one estimated channel coefficient; generating an estimate of input signal power (s o 2) using the received sequence; using the estimated orthogonality factor, estimated disturbance and estimated input signal power to generate an estimate of cell geometry; and using the estimate of cell geometry in processing received data samples.
