Abstract
A wireless transmitter includes a signal processing circuit configured to generate a plurality of first and second spatial streams signals. The transmitter includes a frequency shift circuit configured to selectively apply different frequency shifts to the first and second spatial streams signals. A wireless receiver includes a frequency shift circuit configured to selectively apply different frequency shifts to the received first and second spatial streams signals. The receiver also includes a signal processing circuit configured to process the first and second frequency shifted signals.
