Abstract: The specification and drawings present a new method, system, apparatus and software product for pilot scrambling using a scrambling code (e.g., pseudo-noise code such as a Gold code, a Kasami code, a Hadamard code, m-sequences, etc.) in communication systems, e.g., for wireless communications. The sector/cell specific scrambling codes are mapped to the multiple pilot symbols within, e.g., an SCH (synchronization channel) repetition period. This improves receiver performance on a sector edge and/or a cell edge in, e.g., tight-frequency re-use applications.

Abstract: According to methods and apparatus taught herein, a parametric model of received signal impairment correlations includes a parametric model term that accounts for a dominant receiver but does not result in any significant increase in parametric modeling complexity. In more detail, the parametric model models the dominant interferer as a spatial interferer, which is hypothesized as a point source of interference emanating along single-path channels to each of two or more receiver antennas. The dominant interferer thus is represented in terms of its spatial correlation across receiver antennas. The dominant interferer model term may be included in an overall model fitting process, or it may be fitted separately. Regardless, the spatial modeling approach taught herein may be used for WCDMA and other systems, and may be embodied in essentially any type of linear equalizer receiver structure.

Abstract: A base station apparatus is disclosed, which can efficiently process a reception signal from a user with a simpler constitution. The base station includes: a packet data user control unit that controls packet data for a user and transmits the packet data and notifies a user ID of a user who transmits data in an arbitrary frame (packet transmission period) and a number of this frame; and a layer control unit that manages the frame number and the user ID and controls de-spread and demodulation. The layer control unit creates finger/user allocation information indicating to which user a finger is allocated and outputs the finger/user allocation information to a demodulation unit. The demodulation unit performs demodulation processing using this information such that generated phase compensation data is connected with an identical user and an identical path.

Abstract: Techniques for performing joint detection with a common midamble for downlink transmission are described. In one design, a user equipment (UE) may obtain samples for a burst transmitted by a Node B on the downlink. The burst may include at least one data field and a common midamble. The UE may derive a channel impulse response estimate for each of multiple orthogonal codes based on (i) a channel impulse response estimate derived based on samples for the common midamble and (ii) a traffic-to-pilot ratio (T2P) estimated for that orthogonal code based on the samples for burst. The UE may perform joint detection, for the multiple orthogonal codes, on samples for the at least one data field based on the multiple channel impulse response estimates.

Abstract: Multipath components of signals transmitted through time-varying digital radio channels are received with individual delays, and signals through a given channel comprise a code identifying that channel. A delay profile indicating a magnitude (Y) for delay values in a search window is calculated repetitively for known channels; the delays of multipath components for known channels estimated; a signal strength indicator calculated; and a search for new multipath components not already estimated performed at regular time intervals. When a new multipath component is found, its identification code is compared to the codes of the known channels. If the code of the new component is identical to the code of a known channel, a delay profile and a signal strength indicator is calculated for a window transposed to include the new multipath component. In this way as many multipath components as possible are included in the search window for a new cell.

Abstract: Method for synchronising mobile equipment in a CDMA system comprising a plurality of base stations (11) for communicating with the mobile equipment (12). The base stations (11) are mutually synchronised, and each base station (11) has a synchronisation channel transmit timing offset within a synchronisation time slot (20). The method comprises the step of synchronising the mobile equipment (12) by matching a synchronisation code in the synchronisation time slot (20). Also the following steps are executed by the method: scanning a base radio signal (13) during at least one frame (15) for detecting a signal portion with predetermined characteristics, such as received power peaks (23), the signal portion not being the synchronisation code; deriving timing information associated with the CDMA system from the signal portion; and starting the synchronisation step of the mobile equipment (12) using the timing information.
