摘要:
A receive station of the present invention despreads a received signal over multiple successive symbol periods of an extended measurement period to determine individual channel estimates over each symbol period of an extended period for multiple pilot signals. In one example, the extended measurement period comprises two extended periods, each of which comprise two symbol periods. As a result, the present invention provides channel estimates sufficient for both slow and fast fading conditions. The receive station determines a combined channel estimate for the pilot signals over each symbol period of an extended period by despreading the received signal over each symbol period of an extended measurement period using a common spreading sequence. Based on the combined channel estimates, the receive station determines individual channel estimates for each pilot signal over each symbol period of the extended period.
