PROBLEM TO BE SOLVED: To provide a technique for the improved processing of information provided in an environment, where a non-uniform interference signal exists, in a communication system. SOLUTION: An FM HIBOC DAB system 200 is provided with a transmitter and a receiver. As a digital part of the system 200, a PAC audio coder 202 compresses a coded audio signal, generates that signal into bit rate of 96 kbps and supplies it to a CRC encoder 204. This output is supplied to a channel coding and modulation subsystem 210. A demodulated and decoded received signal is applied to a CRC decoder 212, an error symbol is generated and supplied through an output 242 to a preceding step and a continuous noise erasing process is provided. The error symbol is further used for the triggering of a conventional error recovery process in the PAC audio decoder 214 as well. The audio signal reproduced from the decoder 214 is converted into audibly sensible form by an output device 216.
