International Telemetering Conference Proceedings / October 21, 2002 / Town & Country Hotel and Conference Center, San Diego, California / This paper will present measured data in an adjacent channel interference (ACI) environment for
filtered continuous phase frequency shift keying (CPFSK or FM), multi-h continuous phase
modulation (multi-h CPM or CPM for short) [1] and Feher’s patented quadrature phase shift keying
(FQPSK-B) [2]. This paper is an extension of my 2001 International Telemetering Conference
paper on this topic [3]. 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 CPFSK, CPM, or
FQPSK-B signals. The results presented in this paper will be for a desired signal bit rate of 5 Mb/s,
one interferer 20 dB larger than desired signal (a few tests included two interferers), and various
center frequency spacings, interfering signals, receivers, and demodulators. The overall 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 with minimal interference in the telemetry bands.
