Abstract: Systems and techniques are presented for detecting touch inputs on a touch screen with improved accuracy. Raw sensor readings are received from a plurality of proximity sensors that detect an external object to the touch screen. An equalization is applied to the raw sensor readings. The equalization takes into account an equalization profile indicative of one or more responses from one or more proximity sensors to a reference object positioned in known proximity to the touch screen. Equalized sensor readings are generated based on applying the equalization to the raw sensor readings and positional data is generated based on the equalized sensor readings.

Abstract: An apparatus, method, and computer program product operable to determine a phase of a beamforming weight vector utilizing a memory of a previously used phase for the beamforming weight vector, capable of improving a channel estimate. A base station (320) transmits a beamforming weight vector to a user equipment (310) based on a determined channel estimate. The user equipment (310) selects between the received beamforming weight vector, or a modified beamforming weight vector having its phase shifted by -360, in accordance with a suitable selection criteria. That is, the selection is made such that a difference between the phase of the selected beamforming vector and a phase of a prior beamforming vector is within a predetermined range.

Abstract: A base station receiver (610), a computer program product operable at a base station (600), and a method operable at a base station receiver (610), for receiving uplink transmit diversity transmissions utilizing a master/ slave scheme at the receiver (610). One or more tracking loops, such as a searcher task, a time tracking loop, or a frequency tracking loop may be implemented at the base station receiver (610) to determine compensation values, such as finger timings for a rake receiver or frequency compensation values, in accordance with characteristics of a primary pilot channel (514) transmitted utilizing a first precoding weight vector. Here, corresponding compensation values may be derived for the reception of a secondary pilot channel (520) transmitted utilizing a precoding weight vector orthogonal to the first precoding weight vector, simply based on those determined for the primary pilot channel (514). That is, the compensation value assignment for receiving the second pilot channel may act as a slave to its master, being the
