Abstract :
This paper presents the design and PLD implementation of a multi carrier group demultiplexer for 8, 16, and 32 channels based on the Polyphase-FFT architecture. The circuit implementations she based on Altera´s EPF10K250 SRAM PLD devices. Circuit simulation results presented confirm that the group demultiplexer circuits, operating over a fixed frequency bandwidth and configured for 8, 16, and 32 channels support the intended signal data rates of T1, T1/2, and T1/4 respectively. The group demultiplexer implementations presented here are intended to form the building blocks of a reconfigurable unit capable of supporting different data rates
