Abstract:
1. In a communication system receiver utilizing a local carrier signal and a local code to respectively determine a carrier frequency of a received signal and a phase and rate of a received signal code, wherein the received signal carrier frequency and code rate each reside within a respective uncertainty region, a signal acquisition unit to acquire a transmitted signal including a code comprising: a frequency band module to determine a quantity of frequency bands to employ for said local carrier signal to acquire said transmitted signal, wherein said frequency band module includes a band determination module to identify a quantity of frequency bands sufficient to cover said frequency uncertainty region and a quantity of frequency bands sufficient to cover said code rate uncertainty region, to compare said frequency band quantities for said frequency and code rate uncertainty regions to each other and to select the frequency bands associated with the greatest quantity as said determined quantity of frequency bands to acquire said transmitted signal; and an acquisition module to employ said determined quantity of frequency bands for said local carrier signal to determine said transmitted signal carrier frequency and said phase and code rate of said transmitted signal code in order to acquire said transmitted signal.
