摘要： A mobile device comprises multiple receive antennas to receive spatially independent multipath signals from multiple transmit antennas located on a single base station. The mobile device concurrently generates a RAKE-based equivalent single path signal (RAKE ESPS) and an equalizer-based equivalent single path signal (equalizer ESPS) for the multipath signals received via each receive antenna. The generated RAKE ESPS or the generated equalizer ESPS is selected for channel decoding. Reference signal components are extracted from the multipath signals received to determine noise components, which is used to determine signal quality information of the generated RAKE ESPS and the generated equalizer ESPS. A final ESPS is selected from the generated RAKE ESPS and the generated equalizer ESPS based on the corresponding determined signal quality information. The selected final ESPS is diversity processed by combining signal components over the transmit/receive antennas. Transmission parameters are determined for channel decoding the combined signals.

摘要： Method and apparatus for computing a noise power estimate in a wideband CDMA (WCDMA) network are disclosed and may include calculating a noise power estimate for a downlink channel based on an orthogonal sequence generated for a transmitted signal. The orthogonal sequence may be generated based on a slot number of the transmitted signal and/or a transmit diversity mode used for the transmitted signal. A portion of a plurality of dedicated physical channel (DPCH) pilot bits for the downlink channel may be summed to generate an in-phase (I) component and a quadrature (Q) component. The generated I component and the generated Q component may be multiplied by the orthogonal sequence to generate at least one noise I component and at least one noise Q component.
