Abstract
The invention relates to a device and a method for determining a symbol during reception of a signal coupled with a quadrature signal pair having a discriminator for the determination of a symbol with an analysis of a received signal in complex coordinate space, and a control loop for QAM frequency control and/or rotation control while control parameters are used, which are constructed and/or controlled depending on at least one of the symbols to be decided by the discriminator so that the control parameters are adjusted for decisions to be taken later, wherein one weighting device is constructed and/or controlled, providing in each case one weighting value for the symbols to be decided and/or decided by the discriminator among a plurality of weighting values depending on the symbol position in the complex coordinate space for the control loop.
