摘要： A method and system for estimating the signal-to-interference plus noise ratio (SINR) of the common pilot channel (CPICH) in a W-CDMA receiver. The SINR estimation is carried out after chip level filtering and then the despreading of the CPICH channel. In the case of space-time transmit diversity, a virtual space-time decoding is used on the CPICH channel in order to mimic data channel data channel space-time transformation. The estimated SINR can be used for a User Equipment to report its channel quality indicator to a Node B.

摘要： A digital spread spectrum communication system calculates phase and frequency error (119) on a received signal from a communicating entity during a wireless communication and pre-corrects a signal for phase and frequency error prior to transmission to that entity. Moreover, a carrier offset correction (149) is performed, either at a chip, or at a symbol level.

摘要： Determination of a signal loss profile relative to a receiver based on measured signal power of a sounding signal from a sounding transmitter having a known signal power in free space relative to the receiver. The signal loss profile may include a plurality of signal loss values corresponding to a plurality of received sounding signals at the receiver. In an embodiment, the sounding signal may comprise a GNSS navigational signal (e.g., a GPS signal). The signal loss profile may be used to extrapolate signal loss for a transmitter collocated with the receiver. In turn, the signal loss profile may be used in conjunction with a shared spectrum system to model a signal propagation from the collocated transmitter when determining allocation of a shared spectrum resource of the shared spectrum system.

摘要： A base station receiver, a computer program product operable at a base station, and a method operable at a base station receiver, for receiving uplink transmit diversity transmissions utilizing a master/slave scheme at the receiver. 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 to determine compensation values, such as finger timings for a rake receiver or frequency compensation values, in accordance with characteristics of a first received pilot channel transmitted utilizing a first precoding weight vector. Here, corresponding compensation values may be derived for the reception of a secondary pilot channel transmitted utilizing an precoding weight vector orthogonal to the first precoding weight vector, simply based on those determined for the first pilot channel.
