摘要： Embodiments provide a data transmitter having a transmitter configured to transmit a signal, wherein at least one signal parameter of the signal depends on an environmental parameter in an environment of the data transmitter, and a shielding unit configured to shield the transmitter or part of the transmitter from the environmental parameter to reduce a receiver-side reconstructable effect of the environmental parameter on the at least one signal parameter and/or a modifier for modifying the signal parameter configured to modify the at least one signal parameter to reduce a receiver-side reconstructable effect of the environmental parameter on the at least one signal parameter, wherein the modifier for modifying the signal parameter is configured to modify the at least one signal parameter directly or a signal derived from a clock signal of a clock generator of the data transmitter on which the signal or generation of the signal depends, in order to modify the at least one signal parameter.

摘要： The invention refers to a transmitter that emits data in the form of a group of at least two partial telegrams that together include the data and that are shorter than an individual telegram comprising the data. The transmitter emits the group of partial telegrams according to a hopping pattern that refers to times and/or transmission frequencies of the emission of the individual partial telegrams. Furthermore, the transmitter emits the group of partial telegrams several times and at least twice. Furthermore, the invention relates to a receiver and corresponding methods.

摘要： Embodiments provide transfer methods. The method includes a step of transferring data of a first class from a data transmitter to a data receiver, wherein the data of the first class is transferred divided onto a first plurality of sub-data packets using a first hopping pattern. Furthermore, the method includes a step of transferring data of a second class from the data transmitter or a different data transmitter to the data receiver, wherein the data of the second class is transferred divided onto a second plurality of sub-data packets using a second hopping pattern, wherein transmission pauses between sub-data packets transferred according to the first hopping pattern are smaller than transmission pauses between sub-data packets transferred according to the second hopping pattern.

摘要： In embodiments, data transmitters and data receivers use, in a first mode, a first hopping pattern and a second hopping pattern for a repeated transfer of data, and, in a second mode, a third hopping pattern for the single transfer of data, wherein the hopping patterns of the first mode and the second mode are different so that a collision probability in the repeated transmission of data by a further data transmitter in a respectively different mode may be decreased and the transmission reliability may therefore be increased.

摘要： Embodiments provide a base station of an uncoordinated wireless communication system, wherein the communication system is configured to communicate in a radio band used by a plurality of communication systems, wherein the base station is configured to receive an uplink transmission from an end point of the wireless communication system, wherein the base station is configured to transmit, in response to the reception of the uplink transmission, a downlink transmission to the end point in a downlink transmission window, wherein the downlink transmission window is synchronized in time to the uplink transmission, wherein the base station is configured, in case of an expected collision of the downlink transmission with another transmission, to reposition the downlink transmission in time and/or frequency within the downlink transmission window, in order to avoid a collision of the downlink transmission with the other transmission.

摘要： A data receiver configured to receive a signal having at least two partial data packets, the data receiver being configured to estimate a state of a transmission channel, to obtain first channel state information, to demodulate a first set of received symbols from different data packets, to obtain a first set of received encoded bits, wherein the data receiver is configured to decode the first set of received encoded bits to determine, a first set of estimated encoded bits which corresponds more likely to a first set of transmitted encoded bits than the received encoded bits, and to map the first set of estimated bits to estimated transmission symbols using a mapping rule matching a transmitter-side mapping rule to obtain a first set of estimated transmission symbols, and to determine second channel state information using the first set of estimated transmission symbols.
