Abstract :
We generalize our previous work and present a generic block code design based on a metric-spectrum. That is, based on the communication system and the metric dominating its pairwise error probability, we employ various code search methods to come up with good codes for the corresponding communication problem. Besides generalizing the design methodology, we present also new good complex codes for the AWGN channel as well the coherent Rayleigh fading channel, based on existing and new unitary matrices.
