Document Type and Number:
Japanese Patent JP2001505027
Kind Code:
A
Abstract:
The invention relates to a method of optimizing transmission, and a transmitter receiving digital signals, in which the transmitter is used in a radio system to optimally transmit the signals. The transmitter includes modulation means arranged to modulate the received signals, and converter means for converting the digital signal into an analog signal before signal transmission. The position of the signal received by the converter means within the dynamic range of the converter means affects optimality of the signal obtained from the conversion. The transmitter further include means for generating weighting coefficients, and means 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. In addition, the transmitter includes means for combining the weighted signals, after which the converter means converts the combined signal into an analog signal, and means for scaling the signal converted into the analog signal into a predetermined power level.
