Pattern detection IP operates across multiple, interleaved data streams
The Correlator AX provides the ability to simultaneously analyse thousands of input channels obtained from different carriers in real time using advanced parallel processing. It can search for up to two Unique Patterns (UPs), up to 1024 words long, on each channel and provides reliable identification with a low False Alarm Rate.
The Correlator AX uses both cross-correlation and auto-correlation techniques to provide maximum performance. This makes the new IP suitable for big data searches, electronic warfare signal detection, cyber monitoring, communications, instrumentation, 1-D image correlation and Physics research.
The Correlator AX IP is designed to interface directly with RFEL’s ChannelCore Flex to provide a seamless, high performance solution for signal processing and detection.
Advanced features include partitioned correlation to mitigate frequency errors, cross correlation with user-defined UPs, and auto-correlation is provided to normalise the cross-correlation result so that the detection process is governed by just the pattern of the input sequence and not by its overall power level. Cross-correlation is performed by continuously assessing the channel input data stream (sample-by-sample) with the expected UP. The output consists of the interleaved channel data and time-aligned correlation coefficients.
Oversampled data streams can be supported for communications applications. The Correlator AX core will be available in Q1 2016, with initial support for Xilinx 5, 6, 7 and Ultrascale families with Altera to follow. The Correlator AX is supported by a detailed bit-true MATLAB model of the processing.
