Method and system for combining OFDM and transformed OFDM

A transmitter operating in a communication station, the transmitter comprising:

• circuitry configured to perform a set of operations, wherein the set of operations includes:
• selecting a portion of a two-dimensional resource space, wherein a first dimension of the resource space corresponds to frequency, wherein a second dimension of the resource space corresponds to time;
• applying a first transform to first symbol data to obtain first transformed data, and applying a first inverse Fourier transform to the first transformed data to obtain first output data, wherein the first transform is selected from a set of distinct transformations including the identity matrix and one or more non-identity matrices;
• applying a second transform to second symbol data to obtain second transformed data, and applying a second inverse Fourier transform to the second transformed data to obtain second output data, wherein the second transform is also selected from said set;
• transmitting a first signal from a first antenna of the communication station, wherein the first signal carries the first output data in said selected portion of the two-dimensional resource space;
• and
• transmitting a second signal from a second antenna of the communication station, wherein the second signal carries the second output data in said selected portion of the two-dimensional resource space.
