Abstract :
A prototype of an interference rejection system for OFDM communication was implemented. It comprises a four antennas adaptive receive beam-former with null steering capability and a turbo coded OFDM communication link, both implemented as Globally Asynchronous Locally Synchronous (GALS) system in FPGA, and the analog and radio frequency modules. The system performed well in a radio-frequency laboratory setting over emulated delay and Doppler spread channel in the presence of an interfering signal.
