Title: Derivation of eigenvectors for spatial processing in mimo communication systems
Inventor: KETCHUM JOHN W
IPC: H04B7/04
Filed: 2003-12-09
Granted: 2014-12-09
Abstract: Techniques for deriving eigenvectors based on steered reference and used for spatial processing. A steered reference is a pilot transmission on one eigenmode of a MIMO channel per symbol period using a steering vector for that eigenmode. The steered reference is used to estimate both a matrix .SIGMA. of singular values and a matrix U of left eigenvectors of a channel response matrix H . A matrix U with orthogonalized columns may be derived based on the estimates of .SIGMA. and U, e.g., using QR factorization, minimum square error computation, or polar decomposition. The estimates of .SIGMA. and U (or the estimate of .SIGMA. and the matrix U ) may be used for matched filtering of data transmission received via a first link. The estimate U of or the matrix U may also be used for spatial processing of data transmission on a second link (for reciprocal first and second links).

Patent CA-2569720-C (CA)
Inventor: HAIM JOHN W
IPC: H04B1/707
Filed: 2001-07-12
Granted: 2013-04-23
Abstract: A system and a method of controlling transmitter power in a wireless communication system in which user data is processed as a multirate signal having a rate N(t) and in which the user data signal having rate N(t) is converted into a transmission data signal having a faster rate M(t) for transmission. The transmission power is adjusted on a relatively slow basis based on quality of data received by a receiver of the transmitted data. The transmitter power is determined as a function of N(t)/M(t) such that a change in the data rate in the multiple channels or the rate of the transmission data signal is compensated in advance of a quality of data based adjustment associated with such data rate change. Preferably, the user data signal having rate N(t) is converted into the transmission data signal having the faster rate M(t) by repeating selected data bits whereby the energy per bit to noise spectrum density ratio is increased in the transmission data signal.
Patent CA-2570343-C (CA)
Title: Robust erasure detection and erasure-rate-based closed loop power control
Inventor: SUTIVONG ARAK
IPC: H04L1/00
Filed: 2005-06-07
Granted: 2012-01-31
Abstract: Techniques for performing erasure detection and power control for a transmission without error detection coding are described. For erasure detection, a transmitter transmits codewords via a wireless channel. A  receiver computes a metric for each received codeword, compares the computed metric against an erasure threshold, and declares the received codeword to be "erased" or "non-erased". The receiver dynamically adjusts the erasure threshold based on received known codewords to achieve a target level of performance. For power control, an inner loop adjusts the transmit power to maintain a received signal quality (SNR) at a target SNR. An outer loop adjusts the target SNR based on the status of received codewords (erased or non-erased) to achieve a target erasure rate. A third loop adjusts the erasure threshold based on the status of received known codewords ("good", "bad", or erased) to achieve a target conditional error rate.

Abstract: This invention relates to a cylindrical holder member for a bi-directional bulged rupture disc. The support body of the holder has a rim that supports the rupture disc with the concave surface of the disc facing the holder. The support body is provided with a unitary one-piece, centrally creased cutting element that is of generally V-shaped configuration in plan view. The cutting element has a pair of elongated converging leg components with each leg component being connected to and supported by the interior wall surface of the holder body, with each leg component having an arcuate cutting edge. The cutting edges of the leg components merge at the crease in the cutting element to define a central cutting edge peak section. The cutting element is positioned in the holder with the cutting edge peak section extending beyond the rim of the support body into the concave area of the disc. The V-shaped cutting element functions to provide for a fuller and more rapid opening of the disc upon reversal and engagement with the cutting element as compared with prior reverse buckling disc three-knife blade cutter units. The invention has especial utility in food, beverage, and pharmaceutical applications requiring sanitary pressure relief rupture disc structure.
