International Telemetering Conference Proceedings / October 22-25, 2001 / Riviera Hotel and Convention Center, Las Vegas, Nevada / A new class of non-coherent detection techniques for recently standardized Feher patented
quadrature phase-shift keying (FQPSK) systems is proposed and studied by computer aided
design/simulations and also verified by experimental hardware measurements.
The theoretical concepts of the described non-coherent techniques are based on an
interpretation of the instantaneous frequency deviation or phase transition characteristics of
FQPSK-B modulated signal at the front end of the receiver. These are accomplished either
by Limiter-Discriminator (LD) or by Limiter-Discriminator followed by Integrate-and-Dump (LD I&D) methods. It is shown that significant BER performance improvements can
be obtained by increasing the received signal’s observation time over multiple symbols as
well as by adopting trellis-demodulation. For example, our simulation results show that a
BER=10^-4 can be obtained for an E(b)/N(0)=12.7 dB.
