In a method for equalization of a signal which is transmitted via a payload channel taking into account at least one interference channel, the trellis diagram for the interference channel is processed over an interval of time units. The symbols received in the interval of time units are then corrected by means of information which has been obtained during the processing of the trellis diagram for the interference channel. The trellis diagram for the payload channel is then processed over the same interval of time units, using the corrected symbols.

An input protection structure for integrated circuits to be connected between an input and a reference potential includes a resistor. At least one transistor has a collector connected to the input, a base connected through the resistor to the reference potential, and an emitter connected to the reference potential. A semiconductor substrate has a first conduction type. The collector is in the form of a buried collector of a second conduction type in the semiconductor substrate.

An input protection structure for integrated circuits is connected in a semiconductor substrate between an input and an output for a reference potential. The input protection structure includes a first transistor acting as an input transistor and a second transistor acting as a trigger transistor. The input transistor and the trigger transistor are connected in a cascade. The input transistor and the trigger transistor have a common collector forming the input of the protection structure. The input transistor has an emitter connected to the output for the reference potential. An oxide isolation is provided for adjacent components.

A method for calculating a modulo operation a mod p uses a table (1) containing the values n*p for n=1, 2, . . . . In this case, a and p are positive integers where a mod p=a−n*p. An integral hypothesis nH is calculated for the unknown value n. Afterwards, the values nH*p and also at least one adjacent value (nH+1)*p and/or (nH−1)*p are looked up in the table (1). 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.

The apparatus contains a counter that is synchronized to the reference time in the mobile station. The counter counts sampled chips of the radio signal to produce a count. The apparatus further includes a controller that controls the processing of the radio signal, activates the processing of the radio signal when the count matches a begin count, and deactivates the processing of the radio signal when the count matches an end count, wherein the begin count and the end count are determined by a signal processor as a function of the time frame offset of the radio signal with respect to the reference time in the mobile station.

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.

An apparatus for readjustment of a sampling time in a radio receiver includes a component for determination of any sampling time error in a discrete-value received signal that emits a sampling time error signal. A filter arrangement is provided that includes a multi-rate filter that filters the sampling time error signal. A correction element receives the discrete-value received signal and the filtered sampling time error signal, and emits a discrete-value received signal whose timing has been corrected in accordance with the sampling time error.
