Abstract:
1. A method comprising: receiving content, at a diversity agent, the content for transmission from a wireless communication system having M transmit antennae and N receive antennae and Nc subcarriers, where Nc>>M,N, the received content for transmission from more than two of the M transmit antennae, wherein the received content is a vector of input symbols (s) of size Nc×1, and wherein the Nc subcarriers is the number of subcarriers of a multicarrier wireless communication channel of the wireless communication system; generating a rate-one, space-frequency code matrix from the received content for transmission via the more than two of the M transmit antennae by dividing the vector of input symbols into a number G of groups to generate subgroups and multiplying at least a subset of the subgroups by a constellation rotation precoder to produce a number G of pre-coded vectors (v wherein the diversity agent comprises an encoder to generate the rate one, space-frequency code matrix from the received content using a space frequency code; and wherein the method further comprises the encoder applying the space frequency code to the received content to generate the rate-one, space-frequency code matrix, wherein the space frequency code only consumes one multicarrier communication channel block duration.
