Receivers and methods for reducing an interference component in a receive signal
First Claim
1. A receiver for reducing an interference component in a receive signal, wherein the interference component is caused by a first interferer emitting payload data and a second interferer emitting only broadcast data for communication control, the receiver comprising:
- a first compensation circuit configured to generate a first compensation signal based on a component of the receive signal received from the first interferer;
a second compensation circuit configured to generate a second compensation signal based on only a-priori knowledge of at least one broadcast channel carrying the broadcast data, or based on a detection of symbols in the receive signal which represent the broadcast data, wherein the detection of symbols is based on only the a-priori knowledge of the at least one broadcast channel, anda combination circuit configured to combine the receive signal, the first compensation signal and the second compensation signal.

Abstract
A receiver for reducing an interference component in a receive signal is provided. The interference component is caused by a first interferer emitting payload data and a second interferer emitting only broadcast data for communication control. The receiver includes a first compensation circuit configured to generate a first compensation signal based on a component of the receive signal received from the first interferer. Further, the receiver includes a second compensation circuit configured to generate a second compensation signal based on only a-priori knowledge of at least one broadcast channel carrying the broadcast data, or based on a detection of symbols in the receive signal which represent the broadcast data. The detection of symbols is based on only the a-priori knowledge of the at least one broadcast channel. The receiver also includes a combination circuit configured to combine the receive signal, the first compensation signal and the second compensation signal.
