Abstract

The invention relates to a method of optimizing transmission, and a transmitter receiving digital signals, which transmitter is used in a radio system to optimally transmit the signals, the transmitter comprising modulation means (110) arranged to modulate the received signals, and converter means (120) converting the digital signal into an analog signal before signal transmission. The position of the signal received by the converter means (120) within the dynamic range of the converter means (120) affects optimality of the signal obtained from the conversion. The transmitter comprises means (130) for generating weighting coefficients, means (190) for weighting each modulated signal by a specific weighting coefficient so as to set the mutual power levels of the signals into predetermined relations and to optimally dispose the signals within the dynamic range of the converter means (120). In addition, the transmitter comprises means (140) for combining the weighted signals, after which the means (120) convert the combined signal into an analog signal. The transmitter further comprises means (180) for scaling the signal converted into the analog signal into a predetermined power level.
