Patent ID: 7298777

Claim:
A communication device, comprising: a receiver that receives a plurality of signals; a plurality of searchers coupled to said receiver, said searchers receive a signal from said receiver and decode said received signal; a random access sequence generator coupled to said searchers, said random access sequence generator providing a hypothesis for each searcher to test against the received signal; wherein the hypothesis provided to a searcher is independent of the hypothesis provided to other searchers; and wherein at the searchers an energy accumulation of the received signal is repeatedly compared against a first threshold prior to a maximum limit; and the energy accumulation of the received signal is compared against a second threshold after the maximum limit is reached; whereby a dwell count (duration) of a test varies by increments up to a maximum limit of increments; and wherein the energy accumulation of the received signal plus a BIAS based on a target SNR (signal-to-noise), together, are repeatedly compared against the first threshold.
