Claim:
1. A receiver apparatus for receiving data comprising: reception circuitry configured to receive as an input second multi-carrier signals comprising components of two or more first multi-carrier signals, each of the two or more first multi-carrier signals carrying same data, the same data having been encoded and/or modulated a same way and transmitted using same transmission parameters, and having been distorted by a distortion function applied using filters, the distortion function being different for each of the two or more first multi-carrier signals, and the distortion function introducing a phase distortion by modulating a phase of subcarriers of the two or more first multi-carrier signals; and signal evaluation circuitry configured to evaluate the second multi-carrier signals to which distortion functions have been artificially applied rendering the distortion functions invisible to the receiver apparatus, the signal evaluation circuitry thereby retrieving the two or more first multi-carrier signals.
