Broadband RF front-end and software execution procedure in software-defined radio

A software-defined radio is one of the solutions for realizing a multi-mode terminal for various mobile communication standards. The software-defined radio can be changed by replacement of the application software, including modems, filters, equalizers and so on. A radio terminal architecture fit for the ideal software-defined radio implementation is described. A broadband RF-stage configuration, which introduces the direct conversion principle, is proposed for realizing the multi-mode software-defined radio. A software configuration including the application program which does not depend on the hardware, and the basic programs which reconcile the differences between hardware and execution procedure, are also proposed.
