Stand-alone prototyping platforms

We have a collection of different DSP prototyping platforms featuring FPGA devices, FPGA-based SoCs and also different RF transceiver devices, which allow us to develop and test ultra high-speed/high performance baseband systems. Moreover PHYCOM disposes classic SDR development platforms (high-end laptops connected to signal conversion and RF transceiver devices), reducing the gap between the research concepts  and practical implementations.
