    Abstract: Briefly, in accordance with one or more embodiments, a data packet comprising a first number of bits encoded over a first number of symbols is transmitted to a receiver. If the receiver did not successfully decode the data packet, a negative acknowledgment message is received along with metric information for the transmission. The data packet encoded with a varying number of symbols and transmitted to the receiver, wherein the varying number of symbols is a function of the metric information for the first transmission.

    Abstract: A method of identifying a precoding matrix corresponding to a wireless network channel comprises the steps of identifying a capacity metric that includes an identity matrix, approximating the capacity metric using an approximation metric that ignores the identity matrix, using the approximation metric to search over all matrices in a matrix codebook in order to identify a particular precoding matrix that increases a capacity of the wireless network channel, and transmitting across the wireless network channel a matrix index that corresponds to the particular precoding matrix. Additional techniques for identifying precoding matrices are also described herein, as is a method of approximating a capacity of a wireless network channel in a wireless network.

    Abstract: A method for detecting a preamble location in a multiple preamble OFDM (Orthogonal Frequency Division Multiplexing) system is disclosed. An OFDM signal is generated with a plurality of frames, and each of the frames includes symbols and a predetermined preamble symbol. A maximum FDDC (Frequency Domain Differential Correlator) value is computed for each of the symbols in some of the frames. The preamble location in a frame is determined by summing the maximum FDDC value for each symbol at a same frame location in consecutive frames of the OFDM signal.

    Abstract: An enhanced beamforming with interference nulling method is an improvement over prior art beamforming with interference nulling techniques. The enhanced method includes two scheduling schemes that allow all base stations to schedule their cell edge users independently and determine the information exchange among base stations over the backbone that is needed to support the scheduling activity. The method uses grouping information to perform distributed scheduling among base stations to schedule downlink transmission to cell edge users, while reducing interference to cell edge users served by neighboring base stations. The enhanced method demonstrates the base station-to-base station coordination and information exchange that is needed to enable independent base station scheduling of their cell edge users.

    Abstract: Methods, systems and apparatus for estimating statistical properties of noise in modulated data carrier signals represented by modulated data symbols are disclosed. The method comprises generating an instantaneous estimate of the statistical property of noise from the received modulated data symbols on a sample by sample basis and applying a compensation function to the instantaneous estimate. The method further comprises averaging an output of the compensation function to determine the estimated statistical property of noise.
