Abstract: In this paper,the fast acquisition system of inbound signal in RDSS system was analyzed theoretically. so the optimum detect system for the preamble and the appoximately optimum detect system were derived. The performance of the appoximately optimum detect system was analyzed.The result of experiment indicated that the theoretical analysis and the test result were indendlcal.
