In a star configured multiple access radio communication system wherein a hub station communicates, in time division multiplex mode with a plurality of remote subscriber stations by a forward link signal path and the remote subscriber stations communicate with the hub on a return link that has multiple RF carriers that are configured in an orthogonal manner and wherein all received return link signals are time synchronous, and all signals possess the same time division multiplex structure in which a portion of the signal is dedicated to time synchronization. A synchronization burst sequence generator at each subscriber station, assuming that the time tracking and synchronization process of each return link is relatively unaffected by all other remote stations, generates a sync burst sequence including Sync Codes. The Sync Codes are constructed using a basis sequence of length N, b0, b1, ..., bN-1, with each element in the basis sequence drawn from a binary alphabet {-1,+1}.
