Abstract: Techniques pertaining to anti-motion and anti-interference frame exchange sequences in wireless communications are described. A station (STA), such as a Wi-Fi equipment, determines to enable a frame exchange sequence (FES). The STA then communicates with one or more other STAs by utilizing the FES in which preamble puncturing sounding and data transmission are performed in a same transmission opportunity (TXOP).

Abstract: A physiological signal sensing system and a physiological signal sensing method are provided. The physiological signal sensing system includes a signal processing device and a physiological signal sensing device having a plurality of sensing electrodes. The sensing electrodes are used to contact the skin of an organism to sense a plurality of physiological signals. The signal processing device is coupled to the physiological signal sensing device to receive the physiological signals, compares these physiological signals with the reference physiological signal pattern to obtain a comparison result, selects a selected electrode pair from the sensing electrodes based on the comparison result, and uses the selected electrode pair to perform physiological signal measurement on the organism during a normal operation period.
