Convolutional Coding Options for MFSK/FH Signaling on Rayleigh Fading and Partial Band Interference Channels

摘要

Convolutional coding offers substantial improvement in the bit error probability performance of MFSK/FH modulation when applied to Rayleigh fading or partial band Gaussian interference channels. Using a 4-ary modulation with rate-1/2 codes as a special example, several convolutional coding options are considered, including binary, dual-2, and triple-2 codes. Union-Chernoff upper bounds reveal that improvements of up to 35 dB in (in Eb/N sub o reduction) are achievable at a .00001 bit error probability in comparison to an uncoded system. (Author)
