Abstract
The invention relates generally to the field of signal encoding in a multiple input multiple output system in a wireless communication network. This invention specifically relates to a method of encoding and transmitting symbols in a rate-2 complex symbol per second per Hertz transmission system that achieves a maximum diversity of four for a four transmit antenna system and a diversity of three on a three transmit antenna system. The invention discloses a method 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.
