This paper proposes an ultra-low-power multi-mode baseband transceiver for capsule endoscopy. We set a new specification for capsule endoscopy to achieve ultra-low power and short-latency transceiver. The proposed baseband transceiver can operate multi-mode to transmit ten images per seconds depending on the presence of the lesion and the position...

... we propose the low power multi-mode baseband transceiver that can encrypt the images without memory. Figure 1 shows a block diagram of the proposed multi-mode baseband transceiver for capsule endoscopy. The transmitter consists of a PSDU generator, a PLCP generator, and a signal process unit that can generate a physical layer protocol data unit (PPDU) packet, as shown in Fig. 2. The transmitter sends a 90-bit physical-layer convergence protocol (PLCP) preamble [7], 31-bit PLCP header, and 63-bit physical-layer service data unit (PSDU) by 1 bit according to the transmission order. ...

... last component of PSDU is consists of a MAC header, Encrypted Frame Body, and BCH parity bits. As shown in Fig. 1, the proposed WCE receives images from two image sensors to generate PSDU. The two AES modules encrypt the images received from two complementary metal-oxide-semiconductor (CMOS) image sensors, respectively. The AES modules transfer encrypted images to shortened BCH encoder in binary data. The shortened BCH encoder generates BCH parity ...
