Abstract
In a system in which multiple remote units compete for limited communication resources, a remote unit accesses the system by randomly selecting a first sequence from a set of predetermined sequences. The remote unit transmits a data bit stream modulated with the first sequence beginning at one of a set of recurring admission boundaries. If the remote unit determines that the data bit stream has not been successfully received at a hub station, it randomly selects a second sequence from the set of predetermined sequences. The remote unit transmits the data bit stream modulated with the second sequence beginning at one of the set of recurring admission boundaries.
