Abstract: The present disclosure relates to an add and decode hardware logic circuit for adding two n bit inputs, A and B. A series of n logic stages are each configured to perform a first operation of propagating a result of a preceding stage on the condition that the sum of A[m] and B[m] is equal to 0, wherein 0<=m<n, perform a second operation of performing a bitwise left shift by 2m of the result of the preceding stage on the condition that the sum of A[m] and B[m] is equal to 1, or perform a third operation of performing a bitwise left shift by 2m+1 of the result of the preceding stage on the condition that the sum of A[m] and B[m] is equal to 2. An output at the last stage provides a decoded sum of the inputs A and B.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus that may be used to perform joint spatial processing for space frequency block coding and/or non-space frequency block coding channels in a wireless communications system. In aspects, apparatus and methods are provided for wireless communications, comprising receiving a signal from a serving cell and zero or more interfering cells, and processing the received signal, wherein the processing includes joint processing of at least two Resource Elements (REs), selected to conform to a Space Frequency Block Coding (SFBC) scheme in which transmitted data is modulated across two REs, to detect an interfering cell signal and canceling of the detected interfering cell signal from the received signal.

Abstract: Certain aspects of the present disclosure relate to techniques and apparatus for performing joint demodulation using a Max-Log MAP algorithm in wireless communications systems. An exemplary method generally comprises receiving a signal comprising one or more serving streams and one or more interfering streams; and processing the signal by performing joint demodulation using a max log map (MLM) algorithm for at least one of the one or more serving streams or at least one of the one or more interfering streams.

Abstract: Techniques for deriving a channel estimate using a scattered pilot and a continual pilot are described. The scattered pilot is sent on different sets of carriers in different symbol periods. The continual pilot is sent in each symbol period on irregularly spaced carriers. The scattered pilot is used to identify the indices of channel taps of interest, e.g., L strongest channel taps. The continual pilot is used to determine the complex gains of these L channel taps. A receiver derives a channel impulse response estimate based on received pilot symbols for the scattered pilot, identifies the L strongest channel taps, and determines the indices of these L strongest channel taps. The receiver forms a Fourier sub-matrix based on the L tap indices and determines the gains of the L channel taps based on received pilot symbols for the continual pilot and the Fourier sub-matrix.

Abstract: Systems and methods associated with digitized and automated product management provide for a holistic representation of a product throughout its lifecycle, including physical and non-physical components thereof. More particular features include generation of unit bills of material and application of non-physical components, eg., control parameters, to product units. Features for managing bills of material involve providing a pre-established mapping of technical feature rules that relate commercial feature options for a product to different combinations of technical functions and parts for potential use in a product. Pre-established manufacturing templates are also provided and combined with the mapping to generate an order-specific bill-of-materials, after which point a unit bill-of-materials can be created. Features for digitizing and applying non-physical components, e.g. control parameters, involve establishing a plurality of non-physical components, e.g.

Abstract: Techniques for detecting and suppressing jammers are described. A receiver may perform post-FFT jammer detection and pre-FFT jammer suppression. The receiver may transform an input signal to obtain a frequency-domain signal and may detect for jammers in the input signal based on the frequency-domain signal. The receiver may determine powers of a plurality of carriers based on the frequency-domain signal and may detect for jammers based on peaks in the powers of these carriers. The receiver may filter the input signal (e.g., with a notch filter) to suppress the detected jammers. Alternatively or additionally, the receiver may perform post-FFT jammer detection and post-FFT jammer suppression. The receiver may determine whether jammer is present on each carrier based on data power and channel power for that carrier. The receiver may modify (e.g., zero out or reduce) the frequency-domain signal on carriers with detected jammers.

Abstract: Internal combustion engine with exhaust gas recirculation and turbocharger. The branch (9) connecting the exhaust duct (4) and the inlet duct (5) is situated upstream of the exhaust turbine (6) and downstream of the inlet compressor (7). This branch (9) discharges into the inlet duct via a venturi (10). The regulation of the quantity of exhaust gas is controlled by controlling the exhaust-pressure-regulating devices. These may comprise a turbine with variable geometry.
