Abstract
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.
Claims22
A radio system comprising:
- a front-end receiver for receiving a radio frequency (RF) signal and converting the RF signal into a digital payload signal, wherein said front-end receiver is configured to generate frames each containing data of said digital payload signal and meta data;
- a base-band processor for processing the digital payload signal;
- and
- a serial data interface over which said front-end communicates said frames each containing data of said digital payload signal and meta data in a single digital data stream to said base-band processor,
- wherein said meta data comprises first meta data, and said front-end receiver is configured to generate the first meta data for corresponding digital payload data and to multiplex the first meta data over a plurality of frames.
A method comprising:
- receiving, at a front-end receiver, a radio frequency (RF) signal
- converting, at said front-end receiver, the RF signal into payload data;
- generating, at said front-end receiver, a single digital data stream comprising frames each containing payload data and meta data;
- and
- communicating, via a serial data interface, said digital data stream from said front-end receiver to a base-band processor,
- wherein said generating comprises multiplexing a first portion of said meta data over a plurality of said frames.
A radio system comprising:
- a front-end receiver, wherein said front-end receiver is configured to:
- receive a radio frequency (RF) signal:
- convert the RF signal into payload data;
- generate a single digital data stream comprising frames each containing payload data and meta data;
- and output said digital data stream via a serial data interface,
- wherein the front-end receiver generates the single digital data stream by multiplexing a portion of said meta data over a plurality of said frames.
