| Abstract(in English) | Various radio transmission systems have recently been commercialized. So, multiband/mode receiver which enable one RF chain to receive some frequency band is important. We proposed an architecture which reduce the circuit size to concurrently cancel co-channel interference and image-band interference. We adopt analogue Hilbert transformers to cancel image-band interference and adaptive array antenna to cancel co-channel interference. Furthermore, we can miniaturize the receiver by mixing all signals at the IF stage and reduce complexty by new algorithm. We also show performance of the proposed system by computer simulation. As a result, image-band interference can caused by some imperfection of Hilbert transformer can be completely canceled. Moreover, co-channel interference can be simultaneously canceled. |
