Transmitter configured to provide a channel capacity that exceeds a saturation channel capacity
First Claim
1. A transmitter, comprising:
- a first number of antennas each spaced from another of the antennas by approximately a distance and configured to provide, at one or more wavelengths that are greater than twice the distance, a channel capacity that exceeds a channel capacity that the first number of antennas would provide if each of the first number of antennas were to have a same transmission profile; and
a signal generator configuredto generate a second number of signals each having a wavelength that is greater than twice the distance, the second number related to a third number of signal pipes; and
to couple each of the second number of signals to a respective one of the antennas.

Abstract
An embodiment of a transmitter includes a first number of antennas and a signal generator. The antennas are each spaced from another of the antennas by approximately a distance, and are configured to provide, at one or more wavelengths that are greater than twice the distance, a channel capacity that exceeds a saturation channel capacity. The signal generator is configured to generate a second number of signals each having a wavelength that is greater than twice the distance, the second number being related to a third number of signal pipes. And the signal generator is configured to couple each of the signals to a respective one of the antennas. Such a transmitter can be a multiple-input-multiple-output orthogonal-frequency-division-multiplexing (OFDM-MIMO) transmitter that can be configured to increase the information-carrying capacity of a channel (i.e., increase the channel capacity) above and beyond a saturation capacity of the channel.
