DAMA CELLULAR RADIO SYSTEM WITH A CHANNEL QUALITY CRITERION

摘要

The invention is a cellular radio system (1) for terminals with narrowbeam antennas (20) that provides demand assignment multiple access channel assignment under a guaranteed channel quality criterion. The invention features an efficient channel assignment algorithm (46) that utilizes a database of measured co-channel interference characteristics of subscriber terminals to eliminate significant co-channel interference in assigned channels. The use of measured terminal interference characteristics eliminates the occurrence of unexpected random occurrence of large co-channel interference in channel assignments thus permitting the use of more spectrally efficient cellular frequency reuse patterns.
