Abstract: A device for demodulating a stream of data symbols being part of a multicarrier data stream is disclosed. In one aspect, the device includes a platform capable of running processes in parallel. On the platform a parallel code is mapped for demodulating the data symbols. The parallel code is arranged for determining, from at least one previously processed symbol, information for demodulating a currently processed data symbol of the multicarrier data stream. The device may further includes a parallelization module for parallelizing symbols or groups of symbols of the stream of data symbols code according to a modulo-N symbol splitting of the stream of data symbols, wherein N denotes the number of processes that can run in parallel on the platform. The parallelization module is arranged for applying the parallelized stream to the parallel code.
