In wireless networks, determining the error bit positions within a packet at the receiver can improve the wireless retransmission efficiency in wireless communications. In this paper, we propose an Error Position Estimating Coding (EPEC) scheme based on Error Estimating Coding (EEC). Specifically, we divide data bits into several groups and indicate the group number individually to implement error...
Underwater acoustic sensor networks (UASNs) are widely used in many application. However, the underwater acoustic channel poses many challenges for reliable data transmission protocol design. In this paper, we propose a new data transmission protocol based on Fountain codes and Selective-repeat ARQ scheme (FSR-ARQ). The new approach utilizes the packet error correction ability of rateless code and...
This paper presents a design of analog Receiver Front End based on IntraBody Communication theory, which mainly concentrates on the high data speed-2.5Mb/s and 5Mb/s, extremely long transmission distance-170cm, these specifications are seldom achieved in previous research but will play significant role and be necessary in the further IBC applications. The ISI issue during long transmission on body...
For communications and networking channels, coding techniques are widely used to correct errors in corrupted messages. The “Quality of Protection” (QoP) that can be provided via error correction directly affects the “Quality of Service” (QoS) experienced by users. The errors are commonly assumed to be substitution or erasure errors. Such systems rely on perfect synchronization so that no bit is deleted...
