Abstract: A method for carrier frequency tracking of a received signal having a burst structure includes dividing each burst into a number of segments. The carrier frequency offset of a first segment within a burst is measured to obtain a first segment carrier frequency offset measurement value. The carrier frequency offset of a second segment within the burst is corrected by a second segment carrier frequency offset correction value based on the first segment carrier frequency offset measurement value.

Abstract: A transmitter is configured to transmit a transmit signal modulated according to a first modulation scheme, the first modulation scheme being associated with a set of first constellation points. The transmitter transmits at least a part of the transmit signal based on a subset of the first constellation points, wherein the subset of first constellation points approximates second constellation points of a set of second constellation points associated with a second modulation scheme. The first and second modulation schemes are different from one another.

Abstract: A method for transmitting data of a plurality of data types between a digital processor and a hardware arithmetic-logic unit with at least one associated table memory, first involves preselecting a base address in the table memory that (base address) is dependent on the data type of the data to be transmitted. This is followed by a read and/or write access to the table memory by taking the preselected base address as a starting point for computing the address used for the read/write access in the table memory for each access operation according to an arithmetic computation rule.

The expressions a?nH*p and also a?(nH+1)*p and/or a?(nH?1)*p are calculated and at least one of these expressions is compared with the value 0. n is thereupon determined.

Abstract: A useful channel trellis diagram is processed in a method for equalization of a signal which is transmitted via a useful channel. A disturbance channel trellis diagram is then processed, with useful channel path information being used as a DF contribution. The useful channel trellis diagram is processed once again, using disturbance channel path information as the DF contribution. When the useful channel trellis diagram is being processed for the first time, access is made to input information which was obtained during the useful channel trellis diagram processing in the previous time unit.
