Query: Convolutionally Coded SNR-Adaptive Transmission for Low-Latency
  Communications   Fifth generation new radio aims to facilitate new use cases in wireless
communications. Some of these new use cases have highly de-manding latency
requirements; many of the powerful forward error correction codes deployed in
current systems, such as the turbo and low-density parity-check codes, do not
perform well when the low-latency requirement does not allow iterative
decoding. As such, there is a rejuvenated interest in noniterative/one-shot
decoding algorithms. Motivated by this, we propose a signal-to-noise
ratio-adaptive convolutionally coded system with optimized constellations
designed specifically for a particular set of convolutional code parameters.
Numerical results show that significant performance improvements in terms of
bit-error-rate and spectral efficiency can be obtained compared to the
traditional adaptive modulation and coding systems inlow-latency
communications.
