| Abstract(in English) | Microwave power transmission systems with high power cause adjacent channel interference. Hence a function is required to continue feeding while detecting and avoiding the radio wave from other wireless systems using adjacent frequency channels. This research aims to avoid the interference from the adjacent frequency channels by estimating the signals from the adjacent frequency channels without the channel state information (CSI) and employing the transmit beamforming by creating nulls in the direction of other system terminals. We evaluate the effectiveness of reducing interference in the direction of other system terminals by computer simulation. As a result, it was clarified that the proposed method can form transmission directivity with SIR = 5dB or more with a probability of 90%. |
