Receiver configured to provide a channel capacity that exceeds a saturation channel capacity
First Claim
1. A receiver, 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 be have a same reception profile; and
a signal analyzer configured to recover information from a second number of signals each received by at least one of the first number of antennas over a respective one of a third number of signal pipes and each having a wavelength that is greater than twice the distance, the second number of signals related to the third number of signal pipes.

Abstract
An embodiment of a receiver includes a first number of antennas and a signal analyzer. 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 analyzer is configured to recover information from a second number of signals each received by at least one of the antennas over a respective one of a third number of signal pipes, and each having a wavelength that is greater than twice the distance, the second number being related to the third number. Such a receiver can be a multiple-input-multiple-output orthogonal-frequency-division-multiplexing (OFDM-MIMO) receiver 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.
