Publication number: 20150381259Abstract: Methods and systems that enhance interference cancellation in communication channels are described. Specialized time domain training sequences and simple cross correlation are used to obtain a channel estimate for use in stacked carrier beamforming and OFDM based spatial beamforming. In certain embodiments, a time domain preamble sequence is provided as an alternative to the conventional frequency domain preamble sequence. The use of a time domain preamble can increase channel estimation performance, facilitating cancellation of co-channel interference. Embodiments include generating a training sequence preamble in the time domain, computing a frequency domain response of the channel using an estimate of its time domain impulse response, and using the frequency domain response of the channel to calculate channel estimation from a cross correlation of data received from the channel against the training sequence.Type: ApplicationFiled: July 20, 2015Publication date: December 31, 2015Inventors: Matthew C.

Publication number: 20150188604Abstract: An exemplary wireless communication network that includes a base that communicates with remote units located in a cell of the network. The base concatenates information symbols with a preamble corresponding to a destination remote unit. One or more remote units communicating with the base each concatenates information symbols with a preamble corresponding to that remote unit. An adaptive receiver system for a base unit rapidly adapts optimal despreading weights for reproducing information symbols transmitted from multiple remote units. A transmitter system for a base unit concatenates information symbols with a preamble associated with a remote unit in the cell. An adaptive receiver system for a remote unit in a communication network rapidly adapts optimal weights for reproducing a signal transmitted to it by a specific base unit in the network.Type: ApplicationFiled: January 6, 2015Publication date: July 2, 2015Inventors: Dale A.

Patent number: 8755475Abstract: Methods and systems that enhance interference cancellation in communication channels are described. Samples are obtained from stacked carriers in a received signal and a data vector is created from the samples. Stacked carriers are selected using a steering vector received during synchronization of the receiver. The steering vector is calculated to obtain cancellation of interference from another receiver and is calculated based on time domain channel estimation. Specialized time domain training sequences and simple cross correlation are used to obtain a channel estimate for use in stacked carrier beamforming and/or for use in OFDM based spatial beamforming. State space or filter-based modeled interpolators or whitening matrix-filters in the frequency or time domain are used for interpolation of the channels to maintain linear beamforming weights as a function of time or frequency. Space time adaptive processing facilitates beamforming of communications signals for OFDM and 802.16 (WiMax) systems.Type: GrantFiled: March 2, 2012Date of Patent: June 17, 2014Assignee: The DIRECTV Group, Inc.Inventors: Matthew C.
