Document Type and Number:
Japanese Patent JP3887316
Kind Code:
B2
Abstract:
The invention relates to methods for determining the separate radio frequency gains for carriers in a multi-carrier transmitter of a radio transmission unit of a radio communications system. In order to enable a simple and accurate estimation of the gains, it is proposed to determine the individual gains (G1-GN) of the different carriers mathematically from different sets of powers (REF1-REFN) at some point in each single carrier unit and the corresponding total output powers of the transmitter. Alternatively, the relation of the powers of the different carriers to each other is determined just before the carriers are combined to a single multi-carrier signal. This relation is used for determining the contribution of the different carriers to the transmission power of the multi-carrier signal and for therefrom determining the radio frequency gains for the different carriers.
