1. A data transmitter of a communication system,
wherein the communication system communicates wirelessly in a frequency band used for communication by a plurality of communication systems,
the data transmitter being configured to split a data packet into a plurality of sub-data packets and to emit the plurality of sub-data packets in correspondence with a hopping pattern,
wherein the hopping pattern is derived from a binary sequence, wherein an autocorrelation function of the binary sequence comprises autocorrelation side maximums with a predetermined maximum value,
wherein a minimum total emission duration within which the plurality of sub-data packets are emitted, and/or a maximum length of the sub-data packets is/are dependent on a minimum value of a difference sequence of a sorted difference number series derived from the binary sequence.
