Abstract

This article describes the construction of block codes derived from trellis termination of a binary catastrophic convolutional encoder. Two construction methods are considered: the Zero Tail (ZT) method and a modified Tail Biting
(TB) method. 4-PSK block coded modulation (BCM) schemes are designed based on the constructed codes. These schemes outperform similar schemes derived from the best non-catastrupltic encoder.
