Abstract:
1. A method, comprising: constructing a transmission code matrix, and transmitting said transmission code matrix, at least partially in parallel, using substantially orthogonal signaling resources and at least three different transmit antenna paths, wherein said transmission code matrix can be expressed as being constructed using at least two transformed transmit diversity code matrices, wherein the two matrix dimensions of said transmission code matrix are greater than the corresponding matrix dimensions of said transformed transmit diversity code matrices, wherein said transformed transmit diversity code matrices can be expressed as being constructed by transforming at least two transmit diversity code matrices using linear transformations, and wherein said transmit diversity code matrices, at least one of which is of dimension greater than one, can be expressed as being formed by modulating at least two at least partially different streams of complex symbols that are obtainable from a single stream of complex symbols by conversion.
