METHOD FOR ADAPTIVELY ESTIMATING THE CHANNEL PULSE RESPONSES OF A MOBILE RADIO CHANNEL

摘要

A method is described for estimating channel impulse responses of a mobile radio channel with a broad bandwidth by a code division multiplexing method, and with a synchronization channel continuously transmitting sequences to mobile radio receivers. The sequences are provided for synchronization of each mobile radio receiver and are known to each of the mobile radio receivers. The transmitted sequences have pilot symbols for identifying the synchronization channel, and the pilot symbols are transmitted at points that are known to the receivers within a time slot. When searching for and identifying the synchronization channel, the pilot symbols and, possibly, further symbols and sequences which are known in the receivers, are evaluated to estimate the delay times and the complex amplitudes, of the mobile radio channel responses.
