Abstract: The signal processing is based on the concept of using a time-domain aliased frame as a basis for time segmentation and spectral analysis, performing segmentation in time based on the time-domain aliased frame and performing spectral analysis based on the resulting time segments. The time resolution of the overall “segmented” time-to-frequency transform can thus be changed by simply adapting the time segmentation to obtain a suitable number of time segments based on which spectral analysis is applied. The overall set of spectral coefficients, obtained for all the segments, provides a selectable time-frequency tiling of the original signal frame.

Abstract: Example embodiments presented herein are directed towards an eNodeB, and method therein, for generating downlink communications in a multiple antenna system. The method comprises transmitting, to a number of user equipments, a plurality of reference signals, where each signal is beamformed in a distinct direction within at least one correlated domain (e.g., elevation and/or azimuth). The eNodeB receives at least one CSI report from a specific user equipment and determines a primary reference signal based on, for example, the at least one CSI report. The eNodeB may thereafter generate downlink communication signals for antenna element(s) and/or subelements of the multiple antenna system. The downlink communication signals are beamformed into a transmitting direction that aligns most closely with a beamforming direction of the at least one primary reference signal, as compared to any other beamforming direction of the reference signals.

Abstract: An apparatus for converting mechanical vibrational energy into electrical power includes first and second collecting electrodes configured for connection to terminals of an electrical load, and an electret placed facing the first electrode. The electret is mounted so as to move relative to the first electrode in one degree-of-freedom in a plane. Relative movement between the electret and the first electrode induces a potential difference across the electrodes. The electret has a continuous layer and a series of protrusions, each of which extends perpendicular to the plane. These protrusions are distributed in the degree-of-freedom with a first pitch, which is smaller than the travel between the first electrode and the electret. The first electrode has faces facing the electret. These faces are distributed in the degree-of-freedom with a second pitch identical to the first pitch.

Waveguides built into the anode body sustain oscillations having phase change coefficients of 2*pi*n radians per section, where n is a positive integer. The magnetron is capable of supporting RF oscillations at frequency harmonics of the fundamental frequency, permitting it to operate at frequencies double or quadruple that of a similarly sized conventional magnetron.

Abstract: A radio network resource controller directs a first network node associated with a first cell region, or a wireless terminal in communication through the first cell region, to measure and report radio resource-related data selected from the group consisting of: resource activity per channel; the number of transmitted power samples that exceed a threshold over a measurement period; and, channel quality samples that exceed a quality threshold. The controller then receives at least one measurement report of the radio resource-related data and, as a function of the radio resource-related data in the first cell region, dynamically reallocates the distribution of resources, such as radio-frequency channels, between the first cell region and at least a second cell region. The invention has a particular advantage in TDD mode of operation where efficient and dynamic interference mitigation is needed to combat the inherent mobile-to-mobile and base station-to-base station interference.

Abstract: A method for estimating a scrambling code used on an uplink of a WCDMA system. The scrambling code is obtained from a Gold code, sum of a first specific M-sequence of the user and of a second M-sequence known from the receiver. After sampling of the signal received at the chip frequency of the scrambling code the successive samples are subject to a differential treatment and the sequence of differential values is multiplied by the second M-sequence. The observables thereby obtained are decoded with the aid of a belief propagation iterative decoding. The decoded values then serve to determine the content of the shift register of the generator of the first M-sequence. One then deduces therefrom the Gold code and an estimation of the scrambling code, ?.
