We present a passive data telemetry system for real-time monitoring of gastric electrical activity of a living subject. The system is composed of three subsystems: an implantable unit (IU), a wearable unit (WU), and a stationary unit (SU). Data communication between the IU and WU is based on a radio-frequency identification (RFID) link operating at 13.56 MHz. Since wireless power transmission and...
To improve compression capacity, motion compensation (MC) is utilized in H.264, which includes 6-tap FIR for 1/2-pel interpolation and 2-tap filter for 1/4-pel interpolation. MC uses up most decoding time, and is the expensive part of H.264 decoder. Some consumer electronics, such as smartphones, may not have enough processing capability to decode high definition video program in real time. MC must...
This paper demonstrates six possible cooperative relays from the procedure of Decode-and-Forward relay, and designs their soft combining schemes accordingly. All these schemes are designed for LTE-A system, by the principle of being compatible and making minimum modification to the current LTE system. Among the co-relay schemes, some of them are with high forwarding efficiency, and some of them are...
Network coded retransmission without soft combining (NC ARQ) has been studied for multicast or for multiple unicast. Some papers also mentioned that the soft combining with NC information will be the proper way to improve the receiving performance. However, some papers didn't mention the detailed combining procedure, and most papers on soft combining used extrinsic information for iterative decoding...
To reduce the temporal redundancy in video frame sequence for the similarity between the current and the prior image, a new video coding algorithm based on zero-tree wavelet with extremely high compression is presented in this paper. A new scheme is presented which employs adaptive strategy based on different motion detected in frame sequence. With the algorithm we have realized the real-time compression...
