Abstract :
This paper presents an overview of the PSK and QAM modulations, two digital modulation techniques. Based on recent development of software tools and FPGA circuits, the present paper improves a solution for implementing the PSK demodulation technique on a Virtex 5 board. The design of a BPSK detector, all digital, implemented on the FPGA is also considered.
