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. The invention equally relates to corresponding radio transmission units and modules of such radio transmission units.

A Digital Phase-Locked Loop (DPLL) involves a Time-to-Digital Converter (TDC) that receives a DCO output signal and a reference clock and outputs a first stream of digital values. Quantization noise is reduced by clocking the TDC at a high rate. Downsampling circuitry converts the first stream into a second stream. The second stream is supplied to a phase detecting summer of the DPLL such that a control portion of the DPLL can switch at a lower rate to reduce power consumption. The DPLL is therefore referred to as a multi-rate DPLL. A third stream of digital tuning words output by the control portion is upsampled before being supplied to the DCO so that the DCO can be clocked at the higher rate, thereby reducing digital images. In a receiver application, no upsampling is performed and the DCO is clocked at the lower rate, thereby further reducing power consumption.
