초록

Hardware implementation of a 32-channel MFC digital receiver has not been easy and simple, because it requires real time processing of PCM data. In this paper, we introduce a method of designing an MFC digital receiver compactly by the channel distribution method. We have implemented the MFC digital receiver to process many cnannels by distributing channels of the TDM input data directly to the commercial digital signal processor chips(NEC uPD7720), and by carrying out the modified Goertzel Algorithm. The design of low cost, reliable, high speed, and compact MFC receiver will be shown.
