Title: Bit Flipping in LDPC/Turbo Decoding
Inventor: ISMAIL MOHAMED RAFIQ
IPC: H03M13/11
Filed: 2011-01-14
Abstract: A Low Density Parity Check (LDPC)/Turbo decoder performs a first parity check 101 based on different parts of a parity check matrix and, if the first check fails, inverts the sign (   flips   ) bits 104 whose estimated likelihood 103 falls below a threshold (Î i<Î»i) determined by a gradient descent inversion function, before carrying out a second parity check.Â  The threshold may be lowered (as in Adaptive Threshold Bit Flipping, ATBF) by a factor Î¸<1 and the corresponding syndrome (ie. non-zero elements of ith row of fig. 2) updated before this second check. The parity check matrix is divided into D blocks of rows (D=3 in fig. 2), with at most 1 non-zero value in each column within a block, allowing serial (Z=1) or parallel (Z>1) processing of each block.

Title: Noise-cancelling image sensors
Inventor: TAY HIOK NAM
IPC: H01L27/14
Filed: 2009-12-16
Abstract: An image sensor that has a plurality of pixels within a pixel array coupled to a control circuit and to one or more subtraction circuits. The control circuit may cause an output transistor coupled to a pixel to provide a first reference output signal, a common reset output signal, and a first sense-node reset output signal, between which a subtraction circuit may form a weighted difference to create a noise signal. The control circuit may cause the output transistor to provide a second sense-node reset output signal, a light response output signal and a second reference output signal, between which a subtraction circuit may form a weighted difference to create a normalized light response signal. The light response output signal corresponds to the image that is to be captured by the sensor. The noise signal may be subtracted from the normalized light response signal to generate a denoised signal.

Title: Rank considerations when determining a joint precoding matrix for use in a distributed antenna MIMO system
Inventor: KOIVISTO TOMMI T
IPC: H04B7/02
Filed: 2011-09-27
Abstract: The present invention is concerned with transmissions from multiple distributed transmission points to a user terminal. The transmit points and the user terminal each have a multiple-input-multiple-output (MIMO) capability. For example, the present invention could be applied to coordinated multi-point (CoMP) transmissions. The user terminal determines a transmission rank and a precoding matrix for each of at least two transmission points of a plurality of transmission points. A joint transmission rank for a joint transmission involving each of the at least two transmission points is determined. Next, the user terminal selects a joint precoding matrix which provides the joint transmission rank and is based on the precoding matrices of respective transmission points. The user terminals transmits channel state information (CSI) including a description of the selected joint precoding matrix. The pre-coding matrix may be a diagonal matrix or a semi-diagonal matrix. It may include an intra-transmission point precoder and an inter-transmission point combiner. Also disclosed is a transmit point which uses received CSI reports to determine whether to operate in a MU-MIMO or SU-MIMO mode.

Title: Prioritising radio access technologies for measurement based on signal strength of the serving cell
Inventor: MARTIN BRIAN
IPC: H04W36/00
Filed: 2011-10-03
Abstract: A prioritised measurement list is stored in a memory, and each entry in the prioritized measurement list defines a unique combination of frequency layer and radio access technology for a serving cell and for neighbor cells. Based on at least signal strength of the serving cell, there is selected, from a neighbour list according to the prioritized measurement list, a set of entries for measuring according to a selection rule. The selection rule provides: for the case in which the signal strength of the serving cell is relatively high, the selected set is a first set and represents higher priority ones of the prioritized measurement list; and for the case in which the signal strength of the serving cell is relatively low, the selected set is a second set and represents lower priority ones of the prioritized measurement list.
