International Telemetering Conference Proceedings / October 25-28, 1999 / Riviera Hotel and Convention Center, Las Vegas, Nevada / The performance of novel experimental blind equalizers suitable for a large class of
applications including telemetry systems and other wireless applications is described.
Experimental hardware research of these adaptive patent pending Feher Equalizers (FE)
confirms computer simulated data [1]. A two-ray RF selective faded telemetry channel has
been simulated. A dynamically changing channel environment with a selective fade rate in
the 1Hz to 50Hz range has been constructed by laboratory hardware. The Test and
Evaluation (T&E) setup had RF frequency selective dynamic notch depth variations in the
Power Spectral Density (PSD) within the band of the signal of up to 15dB. As an
illustrative example of the adaptive equalizer capability we used a 1Mb/s rate Feher
patented FQPSK [1] Commercially Of The Shelf (COTS) product. Both hardware
experimental results as well as simulation indicate substantial performance improvement
with the utilization of the FE. It is demonstrated that the FE improves for a large class of
frequency selective faded systems the Bit Error Rate(BER) from 10^-2 to 10^-6. Similar
performance improvements are presented for the Block Error Rate (BLER).
