International Telemetering Conference Proceedings / October 20-23, 2003 / Riviera Hotel and Convention Center, Las Vegas, Nevada / An implementation of a Pseudo Error Detection (PSED) system is presented and its
performance in conjunction with smart antenna and smart diversity systems tested and
evaluated. Non redundancy, instant response and relative simplicity make the Pseudo
Error Detectors excellent real time error monitoring systems in smart antenna and smart
diversity systems. Because of the Non-redundant Error Detection mechanism in Pseudo
Error Detectors, we can monitor the error quality without any coding or overhead. The
output of the pseudo error detector in AWGN, selective fading Doppler shift and other
interference environments is directly correlated to the BER and BLER. This direct
correlation makes it a great tool for online error monitoring of a system and can have
numerous applications
In a PSED the Eye diagram from the demodulator is sampled once per symbol. By
monitoring and comparison of the eye at sampled intervals at different thresholds, we
would know if an error has occurred. By integrating this result over a period of time we
can get the averaged error level. The results provided in this paper were obtained and
verified by both MatLab simulations using dynamic simulation techniques and hardware
measurements over dynamic channels.
