چکیده
This paper motivates the application of Software defined radio as the enabling technology in the implementation of future wireless terminals for 4G. It outlines the advantages and disadvantages of SDR in terms of Flexibility and reconfigurability versus computational complexity. To mitigate the expected increase in complexity leading to a decrease in energy efficiency, cooperative wireless networks are introduced. Cooperative wireless networks enables the concept of resource sharing. Resource sharing is interpreted as collaborative signal processing. This interpretation leads to the concept of a distributed signal processor. OFDM and the principle of FFT is described as an example of collaborative signal processing.
