摘要： In accordance with a method for identifying a preamble sequence and for estimating an integer carrier frequency offset, a signal that comprises a preamble sequence from a set of possible preamble sequences is received. A reduced set of integer carrier frequency offset (CFO) candidates may be determined. Cross-correlation operations may be performed with respect to the received signal and multiple candidate transmitted signals. Each candidate transmitted signal may include one of the set of possible preamble sequences. In addition, each candidate transmitted signal may correspond to one of the reduced set of integer CFO candidates. Multiple correlation values may be determined as a result of the cross-correlation operations. The correlation values may be used to identify the preamble sequence and to estimate the integer CFO.

摘要： An embodiment of the present invention is a technique to process signals in a communication system. In one embodiment, a plurality of signal processing units processes signals received from a plurality of antennae. The signal processor units are controlled by operational mode control signals. A channel estimator estimates channel responses using the processed signals according to an operational mode. An equalizer and combiner generates an equalized and combined signal using the received signals and the estimated channel responses. A Carrier to Interference Noise Ratio (CINR) estimator estimates CINR from the equalized and combined signal. The estimated CINR is used to generate the operational mode control signals. In another embodiment, a sub-carrier allocation controller generates sub-carrier allocation signals using an allocation base. A channel status information (CSI) and multiple input multiple output (MIMO) controller generates sub-carrier CSI signals and operational mode control signals using the sub-carrier allocation signals, estimated channel responses provided by a channel estimator, and an estimated CINR provided by an CINR estimator. The operational mode control signals select one of a plurality of antenna paths associated with a plurality of antennae. A transmitter diversity processor generates transmitter diversity signals as a function of at least a mapped signal Mk, the sub-carrier CSI signals, and the operational mode control signals.

摘要： A method and apparatus for channel estimation in wireless communications are provided. After an initial channel estimation and an estimation of the effective channel length (ECL) are performed, a weighting based on the ECL may be applied in an effort to remove noise from the initial channel estimate and provide an estimated channel with increased accuracy. Different weightings may apply for different channel lengths. A threshold may be used during the ECL estimation, and the threshold may be predetermined or calculated in an effort to adapt to different channel environments.
