International Telemetering Conference Proceedings / October 25-28, 1999 / Riviera Hotel and Convention Center, Las Vegas, Nevada / This paper describes the design considerations used by Aydin Telemetry in the
development of its high data rate Feher Patented Quadrature Phase Shift Keying
(FQPSK) [1] frequency agile transmitter. We will address several key areas of interest to
the Telemetry community, such as the use of commercially available VLSI parts to
minimize parts count while maximizing reliability, adaptive filtering to accommodate a
wide range of data rates, and user selectable features to achieve a universal transmitter
design. User selectable features include differential encoder, 15 stage IRIG randomizer,
and 1/2 rate convolutional FEC coding. This paper also addresses the spectral efficiency
that can be achieved using a Class-C amplifier with FQPSK and the measured bit error
rate (BER) performance versus Eb/No.
