Abstract: A device for sensing a touch by measuring a variation in capacitance according to a contact of an object, and measuring a contact position of the object is provided. The device includes a touch screen panel comprising grid electrodes forming a plurality of electrode patterns, the grid electrodes serving as Tx antennas or Rx antennas, a Tx circuit unit connected with the grid electrode to apply an electric signal to the touch screen panel unit, an Rx circuit unit connected with the grid electrodes to sense variations in the capacitance in the plurality of electrode patterns, and a controller configured to control the touch screen panel unit, the Tx circuit unit, and the Rx circuit unit. The Rx circuit unit includes a first operational amplifier, a first feedback capacitor, and a second feedback capacitor. The first feedback capacitor and the second feedback capacitor are connected with the first operational amplifier. Both terminals of the first feedback capacitor and the first operational amplifier are connected through a first switching unit. The first switching unit includes a 1-1 switch and a 1-2 switch, which are controlled to be short-circuited at a first phase of the electric signal. Both terminals of the second feedback capacitor and the first operational amplifier are connected through a second switching unit. The second switching unit includes a 2-1 switch and a 2-2 switch, which are controlled to be short-circuited at a second phase of the electric signal. The controller is further configured to short-circuit the first switching unit and the second switching unit, at different times, to store charges in each of the first feedback capacitor and the second feedback capacitor.

Abstract: The present invention relates to a decoding method of a software modem in a limited memory environment using overlapping fragmentation and progressive decoding, which processes packets in real-time and reduces power consumption in an environment in which memory is limited when the software modem is used, and the decoding method includes: (a) receiving a data packet from the signal processing device, by the software modem; (b) fragmenting the data packet, decoding the fragments by the fragment, and transferring a decoded MAC header to the MAC module, by the software modem; (c) analyzing the MAC header and verifying whether the packet is a data packet transmitted to the MAC module itself or the packet is damaged, by the MAC module; (d) directing, when the data packet is verified, the software modem to perform additional decoding on the data packet, by the MAC module; and (e) directing, when the data packet is not verified, the software modem to drop the data packet, by the MAC module.According to the method as described above, since decoding is performed after receiving only some blocks of a packet, there is an effect of implementing the software modem in an MCU of a low price and a low specification even in a limited memory environment.
