Abstract: Examples of techniques to enable transmission of alarm data in an industrial automation setting using a publish-subscribe communication system within an Open Platform Communications Unified Architecture (OPC UA) framework. In an example, the alarm data, initially encoded in OPC UA format, is collected from an OPC UA server over a client-server communication system. This data is then re-encoded into a target format compatible with a publish-subscribe communication network. The re-encoding process involves decoding a value from the alarm data based on OPC UA specifications and assigning the decoded value to a preidentified field in the target format. The re-encoded alarm data is then assigned to a message payload of a Message Queuing Telemetry Transport (MQTT) packet, which is subsequently published to an MQTT broker.

Abstract: There is described a method of determining an MRC coefficient vector for a RAKE receiver. The method comprises (a) estimating a channel impulse response vector, (b) estimating a noise variance vector, (c) calculating a multiplication factor vector based on the estimated channel impulse response vector and the estimated noise variance vector, (d) calculating a modified channel impulse response vector by multiplying each element in the estimated channel response vector with a corresponding element in the multiplication factor vector, and (e) calculating the MRC coefficient vector as the complex conjugate of the modified channel impulse response vector. There is also described a corresponding device, an UWB receiver, a computer program and a computer program product.
