Abstract: Systems and methods are provided for suppressing interference from a received data signal. A characteristic of a channel is estimated, the channel being configured for transmission of data between a transmitting device and a receiving device having two or more receive antennas. A spatial correlation of interference is determined for the two or more receive antennas based on the channel characteristic. The received data signal is filtered based on the spatial correlation.

Abstract: Systems and methods for estimating characteristics of a channel are provided. A transmission of known reference data is received at a receiving device. The reference data is transmitted over the channel that includes one or more desired layers and one or more interfering layers. Characteristics of the channel are determined based on the known reference data, where the determining includes a joint estimation of the one or more desired layers and the one or more interfering layers. The determining includes selecting certain of the layers to be estimated at each of the known reference data and selecting certain of the layers to be estimated over a range of the known reference data. The determining includes solving an equation to jointly estimate the one or more desired layers and the one or more interfering layers based on the selections. The selections reduce a number of unknown values in the equation.

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.
