摘要

A method and device for a receiver for electromagnetic waves with at least two antennas are proposed by which the multipath effect occurs - disturbances can be effectively suppress, while a part of the antenna signals at least temporarily in some other way can also be used, for example, the possibilities of the rds activities to be able to better utilize. Dollars a for this purpose, a first antenna signal (1) for generating a said playback signal (23), if the quality of the first antenna signal (1) above a defined threshold for the undisturbed reception is - case 1. in this case 1, the quality of the first antenna signal (1) is determined. If the quality of the first antenna signal (1) falls below this threshold 2 - case, a of at least two antenna signals (1, 2), generated new signal y of the generation of said playback signal (23) is based on. In the case 2, the signal quality of the generated new signal y and the signal quality of at least one of the antenna signals (2) is determined. The generated new signal y is as long as the generation of said playback signal (23), as long as the channel for a certain quality of the antenna signal (2) below this threshold, and is evaluated worse than the signal quality of the generated new signal y.
