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.

摘要： A method and system for determining synchronization status in a wide band CDMA (WCDMA) network may comprise calculating a signal to noise ratio (SNR) of a downlink dedicated physical channel (DPCH) based on a plurality of transmit power control (TPC) bits received via the downlink dedicated physical channel (DPCH), wherein the value of at least one of the plurality of TPC bits is not known when at least one of the plurality of TPC bits is received. The transmit circuitry may be controlled based on the calculated signal to noise ratio. The transmit circuitry may be disabled if the calculated SNR of the plurality of TPC bits is below a first channel threshold. The transmit circuitry may be enabled if the calculated SNR of the plurality of TPC bits is above a second channel threshold.

摘要： The method and system for channel estimation in a single channel (SC) single-input multiple-output (SIMO) system described herein may provide a fast and cost effective approach to concurrently determine propagation channel estimates in a single-transmit (1-Tx) and multiple-receive (M-Rx) antennas wireless communication system. A single weight baseband generator may comprise a set generator, a channel estimator, and an algorithm generator. The set generator may generate orthogonal function sequences that may be applied to the M receive antennas and may be utilized by the channel estimator to generate channels estimates. The orthogonal function sequences may be transferred to the channel estimator after a delay. The algorithm generator may generate phase values based on the channels estimates that may be applied to the M receive antennas to improve the system's signal-to-noise performance.
