Patent number: 8472877Abstract: A system and method for Interference Cancellation (IC). One aspect relates to iterative interference cancellation with iterative finger delay adaptation. The interference cancellation method comprises receiving multi-paths of a signal; and performing iterative interference cancellation to remove multi-path interference, wherein the performing iterative IC comprises estimating a Signal-to-Interference-plus-Noise Ratio (SINR) at each of a plurality of pre-determined rake receiver finger delays, and performing successive Channel Estimation (CE) and IC on rake receiver fingers according to their estimated SINRs, and wherein the CE of a next finger does not start until interference of a previous finger is removed from a sample buffer. The method may further comprise improving estimated rake receiver finger delay, and each iteration decreases the amount of interference observed by each finger.Type: GrantFiled: April 19, 2006Date of Patent: June 25, 2013Assignee: Qualcomm IncorporatedInventors: Jilei Hou, Joseph B.

Patent number: 8385388Abstract: A method and system for reconstructing a user's received signal based on knowledge of the user's transmitted signal to yield efficient interference cancellation when there is spatial and/or temporal correlation in the received signal. The invention may be applied to the cancellation of pilot, decoded data and overhead signals. The method may involve a linear combination of the received samples across time, e.g., at a per-chip or sub-chip resolution, and across antennas, and build upon previous work in that the tap weights need not be the sole functions of the de-spreader outputs in the RAKE receiver.Type: GrantFiled: August 9, 2006Date of Patent: February 26, 2013Assignee: Qualcomm IncorporatedInventors: Joseph B.

Publication number: 20130028293Abstract: A base station in a cellular wireless communications system uses one or more control algorithms to control a transmission pattern of a 1xRTT or DO discovery beacon. The transmission pattern enables access terminals using any one of multiple wake-up periods and wake-up offsets to discover all macrocell frequencies in a finite amount of time. In addition, for base stations allocating a single transmit chain to both 1xRTT and DO beacons, the transmission pattern enables a definite maximum discovery time for both 1xRTT and DO beacons for all access terminals entering the base station coverage.Type: ApplicationFiled: January 31, 2012Publication date: January 31, 2013Applicant: QUALCOMM IncorporatedInventors: Vansh Pal Singh MAKH, Chirag Sureshbhai PATEL, Yeliz TOKGOZ, Mehmet YAVUZ, Joseph B.

Publication number: 20120263164Abstract: Methods and systems for adjusting a forward link (FL) signal to interference and noise ratio (SINR) are provided. In an example, a FL SINR is estimated for each user in a plurality of users, on at least one of each user's respective data rate control (DRC) message or each user's respective prior FL SINR value. The respective estimated FL SINR for a user in the plurality of users is increased, if, based on a reverse link acknowledge message, the user has decoded a packet before all symbols in the packet have been transmitted. Remaining control channel power is determined. The estimated FL SINR for all users in the plurality of users is increased if remaining control channel power is less than a low threshold. The estimated FL SINR for all users in the plurality of users is increased if the remaining control channel power is greater than a high threshold.Type: ApplicationFiled: April 14, 2011Publication date: October 18, 2012Applicant: QUALCOMM IncorporatedInventors: Joseph B.

Publication number: 20110035647Abstract: Multiple channels of received data are processed by a multiple channel demodulation and error correction decoding engine. The statistical uncertainty of processing channels with an iterative decoder are averaged across all the channels to reduce the total processing power required of the decoding engine compared to processing each channel with a separate engine. A set of input buffers holds blocks of data for each channel needing decoding. A quality measure is computed on each input block to set the priority and iteration allocation of decoding in the common decoder. The input RF signal is digitized by a broadband tuner that processes some or all of the channels to feed the multiple channel demodulator and decoder. Multiple decoded video data streams are output.Type: ApplicationFiled: August 24, 2010Publication date: February 10, 2011Applicant: ENTROPIC COMMUNICATIONS, INC.Inventors: Donald Brian Eidson, Arndt Joseph Mueller, Joseph B.
