High Performance PSK Demodulator in FPGA for Wireless Communication Receivers

Phase-shift keying (PSK) demodulator is widely used in modern wireless communication receivers for waveform phase demodulation and symbol recovery. Innovative Integration (II) has developed a small footprint (<10% with Xilinx Virtex5 SX95T) PSK demodulation system that performs high speed BPSK, QPSK, and 8PSK demodulation with symbol rate up to 1.4MSPS. Together with II digital radio receiver (DRR) providing powerful channelization technique, the II-PSK-demod core can be flexibly customized as multi-channel parallel demodulation systems or as a high speed single channel broadband demodulator. With Xilinx System Generator, the design of Digital Down Converter (DDC) and the demodulation system can be rapidly prototyped and simulated in MATLAB/Simulink environment. Innovative Integration's MATLAB/Simulink board support package (BSP) allows designers to implement a mature DSP core on X5 series board within hours, which helps to accelerate the development life cycle.
