Flexible-bandwidth radio

In a radio arranged to receive in a radio frequency band, the radio frequency band including a set of n predetermined radio frequency channels, each of the n predetermined radio frequency channels being capable of supporting a predetermined data rate, a method for the radio to receive a set of n modulated signals via the n predetermined radio frequency channels and to form an aggregate signal, the aggregate signal having an aggregate data rate which exceeds the predetermined data rate of any individual radio frequency channel of the set of n predetermined radio frequency channels, the method comprising the steps of:

• (a) receiving said n modulated signals via said n predetermined radio frequency channels, each of the n modulated signals being received on exactly one radio frequency channel;
• (b) demodulating each of the n modulated signals to form n demodulated signals;
• and,
• (c) forming an aggregate signal based on said n demodulated signals,
• wherein said demodulating step (b) and said forming step (c) are performed substantially by a digital signal processor.
