Abstract: A micromechanical sensor, including a micromechanical chip having a first micromechanical structure, a first evaluation chip, having a first application-specific integrated circuit, and a second evaluation chip having a second application-specific integrated circuit. The first evaluation chip and the micromechanical chip are situated in a stacked manner, the micromechanical chip being directly electrically conductively connected with the first evaluation chip and the first evaluation chip being directly electrically conductively connected with the second evaluation chip. The first application-specific integrated circuit primarily includes analog circuit elements and the second application-specific circuit primarily includes digital circuit elements.

Abstract: The disclosure relates to a method for processing a sensor signal. The method has a step of determining complex rotational factors for a fast Fourier transform. The complex rotational factors are determined using a processing rule, at least one sub-quantity of complex rotational factors, which are kept available, of a total quantity of complex rotational factors, which are kept available and are stored in a non-volatile storage unit, and at least one signal property which is derived from the sensor signal. The method also has a step of carrying out the fast Fourier transform on the sensor signal using the determined complex rotational factors in order to provide a processed version of the sensor signal.

Abstract: The present invention is related to a method for data transmission between a transmitter station and a receiver station of a communication system, especially a wireless communication system, employing a transmission scheme based on the principle of receiver orientation, wherein for the generation of low energy transmit signals within the transmitter station expanded landings on multiple representatives of the complex plane are used and wherein each one of the expanded landing is arranged within an expanded domain of the complex plane. The present invention further relates to a transmitter station and a communication system.

Abstract: A sending station forms a send vector from a data vector having N elements by coding with an error correction code with an a-value modulation alphabet and Q elements, with a being a natural number equal to or greater than two, and sends the send vector to user equipment. The send energy able to be used for sending the send vector is distributed to the Q elements taking into consideration at least one characteristic of the error correction code such that the probability of an incorrect decoding of a receive vector received by the user equipment on the basis of the send vector sent is reduced.
