Actual data are normally stored in a parallel form, so that there must be a conversion from parallel data into a serial bit stream. On the receiver side, this serial data stream will be converted back to its original parallel format. The radio channel is not free of noise and disturbances so that techniques for error recognition and error correction must be applied.
