Abstract: The invention relates to a method and arrangement for connecting a processor to an ASIC. In the arrangement, the processor generates control signals employed when the processor reads data from and writes data to the ASIC. The arrangement comprises means (10) for receiving control signals from the processor and generating read and write signals on the basis of the received signals. The means (10) are implemented by an asynchronous state machine that changes its state on the basis of the received signals. The means (10) change their state without a synchronizing clock signal.

Abstract: The invention relates to a reception method and a receiver. Mechanisms are used for generating, at each level, numbers relating to a bit 1 and a bit 2 and representing a probability of a transition metric of survivor paths. Mechanisms are used for separately summing the numbers relating to the bit 1 and the bit 0 of more than one state and representing the probability of the transition metric. Mechanisms are used for generating logarithms of the sums and means for generating a difference of the logic numbers relating to the bit 1 and the bit 0 representing the probability of the transition metric, whereby a received bit can be determined without a correct path tracing phase.

Abstract: The invention relates to a method for generating a signal amplitude behaving according to a desired function and to a converter implementing the method. In the method, a function that is used for controlling the behaviour of a signal amplitude is piecewise linearized to provide straight lines; a slope and a constant term of each straight line is stored in a memory (202 and 203); and a midpoint of each straight line is shifted to form an origin in a common coordinate system. Variable data (213) is used as address data, which is divided into an MSB (207) and an LSB part (208). The MSB part (207) is used for addressing from the memory (202 and 203) the slope and the constant term of the straight line. The LSB part (208) functions as a variable of a common coordinate system of the straight lines. The amplitude is generated by summing in a summer (205) a product determined by the slope and the LSB part to the constant term, the product being generated in means (204) as a selected summing of arithmetically shifted, masked and complemented slopes controlled by the LSB part.

Abstract: A transmitter clips a transmission signal before transmission in order to reduce the strength of at least one peak of the transmission signal exceeding a predetermined threshold. The transmitter includes a clipper having a minimizer, a filter and an adder. The minimizer minimizes of a cost function with respect to an optimization signal, the cost function having weighted terms as a function of the optimization signal. The terms relate to an effective modulation distortion and an effective overshoot exceeding the predetermined threshold. The filter forms a clipping signal by filtering the optimization signal formed as a result of the minimization according to the spectrum emission mask requirements of the radio system. The adder subtracts the clipping signal from the transmission signal.
