Abstract: An apparatus for detecting the end of a communication is disclosed. The apparatus includes an interface circuit for receiving an encoded signal and a carrier signal recovery circuit coupled to an output of the interface circuit. The carrier signal recovery circuit is configured to output a carrier signal of the encoded signal and a second signal that is out of phase with the carrier signal. The apparatus also includes a decoding circuit configured to decode the encoded signal as a function of both the encoded signal and the carrier signal output by the carrier signal recovery circuit. The apparatus also includes a detection circuit configured to detect an indication of an end of a communication in the encoded signal as a function of both the encoded signal and the second signal.

Abstract: The invention provides a clock select circuit and method which uses feedback arrangements between latches in different branches, with each branch for coupling an associated clock signal to the circuit output. An override circuit is provided in one of the feedback arrangements for preventing a latching delay in that feedback arrangement. This enables rapid switching between clocks in both directions.

Abstract: A method for determining an angle of arrival at a communication device is described. The method comprises performing a message exchange between the communication device and a further communication device. The message exchange comprises receiving at least one first message associated with a first frequency at the communication device by means of a first antenna and a second antenna and receiving at least one second message associated with a second frequency at the communication device by means of the first antenna and the second antenna. The method further comprises determining the angle of arrival defined by an orientation of the communication device and a transmission direction of the message exchange, wherein the angle of arrival is determined based on the received first message and the received second message. Furthermore, a corresponding communication device is described.
