Abstract: The present invention is a method and apparatus for mitigating phase noise in data communication systems. The present invention provides effective phase noise mitigation with very low latency by combining the decision feedback equalizer and carrier recovery loop effectively. The phase noise estimate is obtained by calculating the phase difference between the input and output of the decision device (DD) in the decision feedback equalizer (DFE) and then applying a digital phase locked loop (DPLL) on the phase difference. Deriving the phase noise estimate from the phase noise estimation process, phase noise mitigation is obtained by multiplying the phase noise estimate at the input signal of the feedforward filter (FFF) and at the input signal of the DD in DFE. An accurate signal-to-noise ratio (SNR) estimate is also obtained in the process of the filter coefficient update process in the DFE.

Abstract: Wireless communication under IEEE 802.11 standards utilizing carrier specific interference mitigation where an AP or UE employs an ultra-wideband tuner to evaluate available spectrum between several communication bands. Rather than being constrained to communicate in a single communication band, the AP and UEs may utilize more than one communication band to communicate with one another. In doing so, the AP and UE search across several bands and measure interference on a carrier-by-carrier basis across those bands. Either of the AP and UE may select a cluster of carriers for communication, where the cluster of carriers may comprise 1) contiguous carriers in a single sub-channel, 2) contiguous carriers spanning across more than one sub-channel, 3) discontinuous carriers in a single sub-channel, or 4) discontinuous carriers spanning across more than one sub-channel. The mapping between a cluster and its carriers can be fixed or reconfigurable.

Abstract: A system for detecting and correcting for spurious frequencies that may coincide in a bandwidth of interest in an RF metrology system. The system can (1) utilize a deterministic scheme to detect an interference by a spurious frequency and correct the distortion effect or (2) utilize a mixed signal processing architecture to avoid the occurrence of spurious frequency contamination.

The shift of the analog to digital convert sample rate moves an aliased image of the spurious frequency outside of the frequency of interest. The mathematical vector correction removes the distortion and restores the signal of interest.
