Abstract :
This paper describes a Field Programmable Gate Array (FPGA) implementation of a Digital Front End (DFE) block for a Multi-Carrier Multi-Antenna (MCMA) system. The decimation/ interpolation filters used for obtaining the required channel bandwidth are split into several low order decimation/ interpolation stages, each of them being implemented as a polyphase filter. At the receiver, the DFE contains also a frame synchronization block and an automatic gain controller (AGC). The targeted chips are members of Virtex 2 family, area and speed result being provided for each block.
