Abstract

This work addresses the issue of coding for non-standard channel models with an emphasis on capacity-oriented channel analysis and system design. The first channel studied is the Wyner wiretap channel. Channel sounding results were obtained to calculate the capacity for the multi-antenna case of the Wyner wiretap channel to ascertain the potential for secure communication via secrecy coding. The second channel studied is an asymmetric binary crossover erasure channel (ABCEC) with a short-blocklength constraint. The capacity for this channel was derived, and linear codes were chosen and tested. Another study was conducted on the ABCEC within a degraded wiretap channel setup. Coset codes were applied and tested to determine the additional security that coding provided over the security inherent to the degraded wiretap setup. Finally, asymmetric channel coding schemes in the short-block regime are discussed as future work to more closely approach the capacity of the ABCEC.
