Abstract(in English) | Recently, such as cognitive radio which is changing the available frequency band adaptively, the research of advanced wireless communication systems which use a wide frequency band has become popular. In these systems, interference problem is caused frequently by the unwanted signal with strong input level, because receivers has wide receiving band. For such interference signals, it is required to suppress at the front end of the receiver, and it is necessary to detect the interference frequency. In this report, we propose a detection method of the frequency of any high-frequency signal, using a low-speed A/D converter which has two channels. Moreover, we propose simple detection method using a weighted average of interference signal power which is very strong than that of the desired wave, and show the validity by computer simulation. |
