Abstract :
We describe a frequency-hop (FH) packet radio system that employs parallel concatenated trellis coding, or turbo trellis coding, and continuous-phase modulation. This system is spectrally efficient and performs well at low signal-to-noise ratios. When combined with interleaving, turbo coding also provides a FH system with resistance to partial-band interference. We present simulation results for the turbo trellis-coded FH system with noise and partial-band interference. In particular, we study the probability of packet success for different packet sizes and levels of interference. Results show that this turbo trellis-coded system provides three times the capacity of SINCGARS in an AWGN channel and compares favorably with a block-coded system in partial-band interference
