A real-time spectrum analyzer includes an ADC for providing digitized time domain data, an acquisition control unit for selectively acquiring the time domain data, a processing unit and a display unit. The processing unit includes a domain conversion engine configured to convert the acquired time domain data to frequency domain data, first and second display engines configured to generate first and second display data according to first and second display modes, a frequency content based trigger unit configured to generate a frequency content based trigger signal when the frequency domain data meet a first predetermined trigger condition, and a trigger based enabler configured to generate an enable signal for selectively gating the second display engine in response to the frequency content based trigger signal, such that the second display engine stops generating the second display data, while the first display engine continues to generate the first display data.

Filterbank windowing and Fourier transformation are used to distinguish sub-bands of interest from other sub-bands of an input signal. The sub-bands of interest are selected and then subjected to additional windowing and Fourier transformation.

Real-time separation of signal components in spectrum analyzer

A system for analyzing data, such as data representing samples of a received wireless signal, includes a memory controller for storing the data in one or more memory devices, a metadata extractor for extracting metadata in real-time from the data as it is being processed for storage, and one or more processors for analyzing the metadata to identify portions of the stored data having a characteristic of interest, and for processing the identified portions of the stored data.

Method and system of signal analysis by using metadata

An apparatus that includes a base-band input port and a processor and a method for operating the same are disclosed. The base-band input port receives digital base-band communications including a plurality of communication channels utilized in communications between an RF module and a plurality of user equipment (UE) in a cell serviced by that RF module. The processor demodulates specific channels in the digital base-band communications and extracts therefrom information specifying a unique identity for each of the UEs and a temporary identification used for communicating with that UE. The processor also extracts scheduling information identifying when one of the UEs is scheduled to upload information to the RF module and the communication channels over which the information is to be uploaded. The processor does not demodulate others of the communication channels.

A device receives a data signal and a reference timing signal provided from a first clock. The device includes a sample clock that operates independently from the first clock, wherein the sample clock outputs a sample clock signal that is asynchronous with the reference timing signal; a sampler for sampling a data signal in accordance with the sample clock signal and outputting a sampled data signal; and a resampler for resampling the sampled data signal according to a resampling ratio and outputting a resampled data signal such that a number of data samples in the resampled data signal within a synchronization time interval defined with respect to the reference timing signal equals a nominal number of data samples that would occur in the sampled data signal within the synchronization time interval when the sample clock signal was synchronized to the reference timing signal.
