摘要： A method for equalizing and decoding an error-protected data signal transmitted via a radio channel is described. According to the method, an equalized data signal is calculated at the receiving end in a demodulator with a first channel estimator. The equalized data signal is decoded by a decoder to determine a decoded output signal. The equalized data signal is transmitted to a second channel estimator, which repeatedly detects second channel parameters of the radio channel. The parameters are transmitted to the decoder which uses them as calculation parameters during decoding.

摘要： In a method for data transmission on transmission channels in a digital transmission system, turbo coding is carried out in a turbo coder at a transmitter end for channel coding, and turbo decoding with soft-decision output signals is carried out in a turbo decoder at the receiver end. In order to improve the quality of service, the quality of service is determined from the variances of the soft-output signals at the turbo decoder, and the coding rate is set by adaptation of the puncturing such that a predetermined quality of service is obtained. Alternatively, the number of decoding iterations is set as a function of the quality of service. If a MAP symbol assessor is used at the receiver end, the variances &sgr;2LLR of the soft-decision output signals from the turbo decoder are determined, and the bit error rate is calculated from the variances &sgr;2LLR as a measure of the quality of service.

摘要： In a method according to the invention, N data symbols of a subscriber signal form a block. In a first method step, the block is divided into a plurality of partial blocks having Ns data symbols. The Ns data symbols are then allocated to sub-carriers and are modulated in parallel onto the various sub-carriers, the modulation being carried out for each of the sub-carriers with at least one individual code symbol. The sub-carriers are heterodyned to form a broadband carrier, so that the Ns data symbols are transmitted simultaneously. The transmission then takes place in N/Ns successive partial blocks via the radio interface.

摘要： An initial data stream is coded using a first set of n coders to form n coded data streams, which are subsequently punctured by combining the n coded data streams with a first puncturing data field to form a first punctured data stream. The initial data stream is also interleaved using k interleaving circuits to produce k interleaved data streams, which are subsequently coded using a set of m coders to form m coded interleaved data streams. In addition, a second puncturing data field is interleaved to form an interleaved puncturing data field. The m coded interleaved data streams are subsequently punctured by combining the m coded interleaved data streams with the interleaved puncturing data field to form a second punctured data stream. The initial data stream, the first punctured data stream and the second punctured data stream are multiplexed to form a transmission data stream.
