A radio system comprises a front-end receiver for receiving a RF signal and converting the RF signal into a digital payload signal. The system further comprises a base-band processor for processing the digital payload signal, and a serial data interface over which the front-end communicates the digital payload signal and meta data to the base-band processor. The meta data may comprise information indicating whether a corresponding digital payload signal communicated over the serial data interface is valid and additional information of the front-end status, e.g. gain or state of tuning.
