Abstract
This work addresses code design and code selection rules under power and decoding delay constraints for antipodal (BPSK) modulated and convolutkmally encoded communication system. The system operates over a slowly-fading AWGN channel, described here by the ‘block fading’ model. We specialize to coherent detection and maximum likelihood decoding with ideal channel information (the instantaneous fading values). The dominant design criterion in this scenario is the code diversity level in terms of blocks while the standard Hamming distance plays a secondary role. A code design procedure is presented along with a code-search algorithm. Performance results of a selected code are assessed via simulation and compared to those achieved by a Reed-Solomon code with erasure and error decoding.
