Systems and methods for suppressing interference in a signal received by a device having two or more antennas
First Claim
1. A method for suppressing interference from a data signal received at a receiving device, the receiving device having two or more receive antennas, the method comprising:
- estimating characteristics of a channel through which the data signal was transmitted by a transmitting device to the receiving device;
determining, based on the estimated characteristics of the channel, a spatial correlation of interference and noise received at the two or more receive antennas of the receiving device, the spatial correlation indicating how the interference and noise received at a particular one of the receive antennas is related to the interference and noise received at another one of the receive antennas; and
using the spatial correlation of the interference and noise to suppress interference and noise from the data signal received at the receiving device.

Abstract
Systems and methods for suppressing interference from a data signal received at a receiving device, where the receiving device has two or more receive antennas, are provided. Characteristics of a channel are estimated, the channel being a channel through which the data signal was transmitted by a transmitting device to the receiving device. A spatial correlation of interference and noise received at the two or more receive antennas of the receiving device is determined based on the estimated characteristics of the channel. The spatial correlation indicates how the interference and noise received at a particular one of the receive antennas is related to the interference and noise received at another one of the receive antennas. The spatial correlation of the interference and noise is used to suppress interference and noise from the data signal received at the receiving device.
