Abstract
A multiple-access digital radio communication system and method with communication links between user terminal transmitters and central node with a receiver system including a multibeam antenna. User terminal transmitters assigned to one beam coverage region use mltiple access channels that are mutually orthogonal for transmitting digital message information. These multiple access channels are reused in adjacent and other beam coverage regions. Error-correction coding (), interleaving (), and a single-axis modulator () are used in the user transmitter to increase resistance to potential interference from user terminal transmitters in other coverage regions. At the receiver, an adaptive processor () such as an equalizer or sequence estimator is used to combine multiple antenna beam signals () to produce a combined signal associated with each user. Deinterleaving () and error-correction decoding () of the combined signal is used to complete the recovery of the digital message information.
