Interference Elimination Scheme of Wireless Power Transmission for IEEE 802.11 ah
Internet of Things (IoT) plays an important role in managing the information between the systems and sensors installed in the electronic devices. Since some of these sensors are stationed in areas that are difficult to access, the application of Wireless Power Transmission (WPT) is implemented in the charging system. In this system, the power and data are transmitted at a certain time interval. However, the shifting time causes the interference which affected the data signal. In order to eliminate the influence of interference on the data signal, we conduct this study. To realizes this objective, we introduce two approaches which are rearranging the data subcarriers and using high pass filter. Through these methods, it is found that the BER characteristics are improved. Even so, due to nullification of some data subcarriers in the rearrangement method, the data rate decreases. Hence, in terms of data rate speed the application of HPF is proven to be more preferable.
