5203 |a"This report describes the simulation of frequency dehopped binary and 4-ary non-coherent frequency shift keyed signalling (NCFSK) over a Gaussian channel. Orthogonal FSK signals and a hopping rate of one hop per FSK symbol were simulated. Simulations were performed with and without forward error correction. Rate 1/3, constraint length 8 and rate 1/2, constraint length 7 convolutional codes with hard decision Viterbi decoding were used. A family of curves showing the probability of bit error versus Eb/No was produced. Coding gains of about 2 dB at an error rate of 1 in 10⁵ were observed for binary NCFSK and a coding gain of less than 1.0 dB was observed at the same error rate for 4-ary NCFSK. Some extensions of the work are suggested for future study"--Abstract, page 1.
