A method and transmitter for generating a multicarrier signal, to be transmitted to a receiver, are provided. The method comprises dividing symbols to be transmitted into protected symbols and non-protected symbols; precoding non-protected symbols in a first precoder; precoding protected symbols in a second precoder; creating a modified non-protected symbol vector, based on the precoded non-protected symbols and the precoded protected symbols; and modulating the modified non-protected symbol vector and the protected symbols, thereby generating the multicarrier signal. Also, a method and receiver are disclosed.
