TESTS AND EVALUATIONS OF ADAPTIVE FEHER EQUALIZERS FOR A LARGE CLASS OF SYSTEMS, INCLUDING FQPSK

International Telemetering Conference Proceedings / October 23-26, 2000 / Town & Country Hotel and Conference Center, San Diego, California / Design and performance evaluation of a low-complexity equalizer for recently standardized spectral efficient Feher
patented quadrature phase shift keying (FQPSK) system [1] over multipath fading channel is presented. The
implementation based on a Feher patented equalizer (FE) [1] is of a structure with three branches, which are
individually used to compensate for a moving fade notch with different locations. These branches are switched by
the control signal that is generated based on pseudo-error on-line detection technique. It is demonstrated that for
typical aeronautical telemetry RF frequency selective fading channels, having delay spreads in 20 – 200 ns range,
the adaptive FE reduces the number of statistical outages by more than 60% without the need for training bits and
without increasing the receiver synchronization time.
