ADJACENT CHANNEL INTERFERENCE MEASUREMENTS WITH CPFSK AND FQPSK-B SIGNALS

International Telemetering Conference Proceedings / October 22-25, 2001 / Riviera Hotel and Convention Center, Las Vegas, Nevada / This paper will present measured data in an adjacent channel interference (ACI) environment for
both filtered continuous phase frequency shift keying (CPFSK) and Feher’s patented quadrature
phase shift keying (FQPSK-B) [1]. The quantity measured was bit error probability (BEP) versus
signal energy per bit to noise power spectral density ratio (E(b)/N(o)). The interferers were either
CPFSK or FQPSK-B signals. The results presented in this paper will be for bit rates of 5 Mb/s, one
interferer 20 dB larger than desired signal, various channel spacings, and two different telemetry
receivers. The ACI test effort will collect data sets at several bit rates and with one and two
interferers. The results will be useful to system designers and range operators as they attempt to
maximize the number of Mb/s that can be simultaneously transmitted in the telemetry bands.
