Abstract: A coding and modulation apparatus and method are presented. The apparatus (10) comprises an encoder (11) that encodes input data into cell words, and a modulator (12) that modulates said cell words into constellation values of a non-uniform constellation. The modulator (12) is configured to use, based on the total number M of constellation points of the constellation, the signal-to-noise ratio SNR in dB and the number n of the dimension of the constellation, an n-dimensional non-uniform constellation from a group of constellations, wherein each constellation point of an n-dimensional constellation diagram is defined by an n-tupel of constellation values, said n-tupel of constellation values defining parameter settings of a transmission parameter used by a transmission apparatus for transmitting a transmission stream obtained by conversion of said constellation values.

Abstract: The improved beamforming devices for communication systems operating in the mm-wave spectrum are particularly designed for antenna architectures consisting of antenna arrays, comprising multiple antenna array elements. The disclosed approaches comprise intelligent two stage searches, wherein information from the first stage is used in the second stage. This significantly reduces the computational complexity compared to the known approaches, with minimal loss in performance.

Abstract: A communication device for RF based communication with another communication device, said communication device comprising circuitry configured to apply a fine timing measurement, FTM, procedure. The circuitry is configured to determine an FTM mode out of at least two different FTM modes, and to perform an FTM procedure to determine the round trip time, RTT, between the communication device and the other communication device, wherein the RTT is determined by evaluating a time information of a tap of the channel impulse response, wherein the tap used for the evaluation depends on the determined FTM mode.
