摘要： A data transmission method comprises receiving a channel access request to a radio receiving unit from a mobile station of the telecommunication system, and performing an operation on the channel access request using a predefined configuration of devices and algorithms of the radio receiving unit. After filtering the background noise from the channel access request; a characteristic of the channel access request against at least one predefined detection rule, and the channel access request is considered valid if the characteristic of the channel access request fulfils the detection rule. Essentially, the detection rule is not dependent on the configuration of the radio receiving unit.

摘要： A signal receiver includes a sampling device for sampling a received signal carrying a stream of symbols to form a first set of actual samples. The signal receiver also includes interpolation means for interpolating between the samples of the first set to form a second set of interpolated samples. The signal receiver also includes symbol recovery means configured to process the first and second sets of samples so as to form an estimate of the symbols of the signal. The processing includes performing a temporal whitening step on signals derived from first and second sets of samples. The signal receiver also includes signal combining means using a matched filter and averaging technique.

摘要： In a method for equalization of a data signal based on the Viterbi algorithm, trellis contributions are first of all calculated for reconstructed signal values from transition metrics, and are stored in a first table memory. If a reduced trellis diagram is intended to be used as the basis for calculation of the transition metrics, decision feedback contributions are also calculated, and are stored in a further table memory. In the case of ACS operations, the first and, if appropriate, the further table memories are accessed in order to determine the reconstructed signal values.
