Abstract

A method and an apparatus for indication of a modulation, wherein according to the method samples are taken in a symbolic sequence over a time interval of a received signal, after which the samples are fed into two or more parallel-connected modulation indicators 14, 15, for indication of bits, wherein the time interval is divided into several parts, for each part in the respective indicator an error estimate is defined for the signal produced, which describes the error rate of the signal produced, and for each part one selects the indicator that represents the most favourable error estimate, wherein the bits created for each part of the indicator are used in the further processing. <IMAGE>
