A reconfigurable four-channel transceiver testbed with signalling-wavelength-spaced antennas under centralized FPGA control

We propose a novel software defined radio implementation of a four-channel transceiver testbed with signaling-wavelength-spaced antennas. The radio frequency (RF) side of the system will be implemented using commercial off the shelf (COTS) products, whereas the baseband processing portion of the system will be implemented on a pair of Altera Stratix II EP2S180 development boards with high-speed analog devices analog-to-digital converter (ADC) daughter boards. The FPGA will be used to implement DSP algorithms and to affect centralized control over the entire system. A goal is to create a testbed for algorithms and radio channel measurements
