Abstract :
We discuss the design and performance of convolutional codes over non-binary fields, with an eye toward use of orthogonal signaling and noncoherent detection as might be imposed by a frequency-hopping scenario. Orthogonal signaling combined with low-rate coding (convolutional or otherwise) has been shown to afford efficient transmission on AWGN, Rayleigh fading, and partial-band noise channels.
