Design and performance comparison of a superregenerative MPSK transceiver

Abstract

In this paper we present a superregenerative transceiver able to switch among BPSK, QPSK and 8PSK modulations. An HF-band proof-of-concept transceiver is implemented on an FPGA with a minimum of analog circuitry. The desire of making fair comparisons between BER figures rises a problem of clock frequency selection which is finally solved without consuming extra resources.
