Various antennas may benefit from improved signaling. For example, it may be helpful for a signal in a high occupied bandwidth environment to be compressed using a block floating point format, which can also help to reduce power consumption. A method may include separating an incoming signal at a digital front end or a converter into two alternating signals comprising a coarse signal and a fine signal. The method may also include transmitting the coarse signal and the fine signal from the digital front end to the converter or from the converter to the digital front end. The coarse signal and the fine signal may be combined to generate an approximation of the incoming signal.

Bit rate compression for signal transmission

A delay device has at least one first delay element and optional additional delay elements connected downstream from the first in a serially consecutive manner. The digital input signal is connected to an input of the first delay element and is connected to an input of a first D/A converter. The output of the first delay element is connected to an input of another D/A converter assigned thereto. The optional additional delay elements each have outputs connected to an input of another D/A converter assigned to the respective delay elements. All D/A converters are combined on the output side in a step-by-step manner so that output signals of all D/A converters form the analog output signal or the device. A specific coefficient is assigned to each D/A converter, and a specific delay time is assigned to each delay element for realizing a filter characteristic.
