Abstract:
1. Apparatus for providing a modulated signal based on a combined digital signal, wherein the combined digital signal contains information of a first digital input signal and a second digital input signal, wherein a block length of the first digital input signal is shorter than a block length of the second digital input signal, comprising: a bit adder configured to add at least one filling bit to a block of the first digital input signal to obtain an adapted first digital input signal, so that the block length of the adapted first digital input signal is equal to the block length of the second digital input signal; a combiner configured to combine the adapted first digital input signal and the second digital input signal to obtain and provide the combined digital signal; and a mapper connected to the combiner and configured to generate a complex symbol for a block of the combined digital signal based on a selected mapping constellation to obtain and provide the modulated signal.
