Outline of Final Research Achievements

We have proposed a concept of “adaptive baseband radio” as a pioneering wireless transmission system to open a vista shifting away from the long-lasting Marconi paradigm. The proposal adopts the principle of baseband orthogonal frequency division multiplexing (OFDM) to enable the spectrum to be controlled freely for realizing “band-free communications”. An experimental system was constructed and a demonstration experiment was implemented under a multipath-rich environment. The adaptive baseband radio proposed here is a system integrated with functions of cognitive radio and software-defined radio, which exhibit a promising potential.
