AbstractUsing Feher patented Quadrature Phase Shift Keying provides improved spectrum efficiency for high rate telemetry systems. This paper presents an off-line coherent FQPSK-B software reference receiver developed for hardware validation under contract from the Joint Services Advanced Range Telemetry (ARTM) program. This receiver is implemented in Matlab/Simulink that makes it easily configurable for different tasks and very flexible in handling many other types of QPSK signal or their derivatives with simple modifications. It also offers a cost-effective approach for end-to-end system design. The functionality and key features of this receiver (including its internal software transmitter) will be discussed in this paper. Results from end-to-end system simulations are included as examples.
