International Telemetering Conference Proceedings / October 21, 2002 / Town & Country Hotel and Conference Center, San Diego, California / This paper will present the results of some experiments with non-coherent, single symbol detection
of pulse code modulation (PCM)/frequency modulation (FM) where the receiver intermediate
frequency (IF) bandwidth is much wider than the bit rate. The experiments involved varying the
peak deviation and measuring the bit error probability (BEP) at various signal energy per bit to noise
power spectral density ratios (E(b)/N(o)). The experiments showed that the optimum peak-to-peak
deviation was about 0.7 to 0.8 times the –3 dB IF bandwidth and that the E(b)/N(o) required for a given
BEP increased as the ratio of IF bandwidth to bit rate increased. Further, bi-phase-level/FM
performed slightly better than non-return-to-zero-level (NRZ-L)/FM with an ac coupled RF signal
generator and IF bandwidths much wider than the bit rate.
