Block coded modulation using two-level group codes over generalized quaternion groups

This paper deals with Euclidean space codes obtained from two-level group codes of length n over a generalized quaternion group Q/sub m/, m/spl ges/3, with 2/sup m/ elements, with generators x and y, given by the presentation Q/sub m/= using a matched labelling of a 4-dimensional signal set with 2/sup m/ elements with Q/sub m/.
