Abstract

A communication system (205) is provided that includes signal encoding (206) in a multiple input multiple output system. The communication system includes wireless communication networks (250). The communication system (205) includes methods of encoding and transmitting symbols (20B) in a rate-1 complex symbol per second per Hertz transmission system while achieving maximum diversity. The communication further includes methods of interleaving the complex symbols such that each interleaved symbol comprises information of at least two complex symbols where the complex symbols obtain values from a rotated constellation (208).
