Aircraft radio system

An aircraft radio system comprising:

• a plurality of radios, each radio having a transceiver and a dedicated processor platform to carry out waveform processing for the transceiver;
• the dedicated processor platforms being interconnected to one another through a digital communications network such that the dedicated processor platforms constitute a virtual processing environment for the aircraft radio system,
• wherein, within the virtual processing environment, processing of an individual waveform received by a first one of the transceivers is distributed across at least two of the dedicated processor platforms, such that the processing of the individual waveform is carried out in part by the processor platform dedicated to the first one of the transceivers and in part by one or more of the processor platforms that are dedicated to other ones of the transceivers.
