This paper presents a correlation method for processing data on end devices and reducing
the amount of data transmitted over the network. Instead of expensive and complex network
devices, developers can use cheap and proven low-speed Internet of Things (ZigBee, NB IoT,
BLE) solutions for data transfer. The novelty lies in one of the features of this approach: the use
of components for analysis, rather than a complete copy of the signals, as well as processing
directly on the sensor. The advantage of this approach allows you to reduce the number of
operations and complexity of implementation, in contrast to other methods focused on the
cloud computing paradigm. We provide results for correlation values and the number of logical
elements (LE) when implemented on the FPGA, depending on the number of elements in the
correlator. This allows to maintain a balance between the required calculation accuracy and
spent hardware resources, as well as to simplify the end device.
