SMART DIVERSITY RECEIVERS FOR DYNAMIC, MULTIPATH, FREQUENCY SELECTIVE FADED FQPSK AND OTHER SYSTEMSAflatouni, Katayoun, Feher, Kamilo 10 1900 (has links)
International Telemetering Conference Proceedings / October 22-25, 2001 / Riviera Hotel and Convention Center, Las Vegas, Nevada / Design, performance Test and Evaluation (T&E) of a novel smart diversity receiver, based on Feher
Diversity (FD) patents over multipath, fast dynamic frequency selective fading channels is
presented. A hardware simulator for construction of a frequency selective fading channel has been
implemented in laboratory to resemble a telemetry aeronautical channel model, namely the two-path
channel model. As an illustrative example, the block error rate (BLER) of a 1 Mb/s rate IRIG 106-00 and CCSDS standardized Feher’s patented quadrature phase shift keying (FQPSK) [1][2] with
and without diversity in multipath frequency selective fading channels has been tested and evaluated.
The experimental results clearly indicate significant performance improvement with the proposed
diversity technique even in cases of severely distorted channels.
