Abstract
The invention relates to a method and a circuit system for deciding a symbol (S) upon reception of received symbols coupled with a quadrature signal pair (I, Q). For deciding a symbol upon reception of an input signal using received symbols (S) coupled with a quadrature signal pair, wherein phase noise (PN) and Gaussian noise (GN) are superimposed on at least one such received symbol, the phase noise (PN) as well as the Gaussian noise (GN) are determined or estimated for at least one such received symbol (S). This is advantageously achieved by the fact that when the phase noise (PN) and the Gaussian noise (GN) are determined or estimated, a differentiation is made between the phase noise (PN) and the Gaussian noise, and a result of the differentiating determination or estimation is used for controlling reception parameters for decisions concerning subsequently received symbols (S). In particular, the measured values of the phase noise (PN) are orthogonalized to the Gaussian noise (GN).
