Convolutionally Coded Hopping Pattern for MFSK Modulation in Underwater Acoustic Communication

IEEE Access, 2019
A convolutionally coded M-ary frequency shift keying (MFSK) modulation scheme for underwater acoustic communication is introduced. It uses a rate 1/log2 M inner convolutional code, whose coded symbols are used as transmission symbols.
