We investigate the performance of three-node lossy-forward (LF) relaying over independent block Nakagami- $m$ fading channels. Based on the theorem of source coding with side information, the exact outage probability expression for arbitrary values of the shape factor $m$ is derived under the assumptions of both the Gaussian codebook capacity and the constellation constrained capacity. The difference...
The goal of this paper is to provide analytical assessment that justifies the performance tendencies of practical encoding/decoding techniques for a binary data gathering wireless sensor network (WSN). The theoretical rate region of the WSN is approximately analyzed based on the Slepian-Wolf theorem. We also derive the bit error rate (BER) floor given the observation error probability by using the...
This paper investigates the outage behavior of transmitting correlated binary sources with arbitrary code rate over quasi-static Rayleigh fading multiple access channel (MAC). The sufficient condition for lossless communication with arbitrary code rate is obtained by assuming separate source and channel coding, which indicates the two rate regions specified by the Slepian-Wolf theorem and the MAC...
In this paper, we re-formulate an issue related to wireless mesh networks (WMNs) from a Chief Executive Officer (CEO) problem viewpoint, and provide a practical solution to a simple case of the problem. The problem is described as follows: an originator broadcasts its binary source information to several forwarding nodes over Binary Symmetric Channels (BSC); the originator's source information suffers...
The purpose of this study is to investigate plausible central and peripheral coding strategies of joint angle by descending γs commands and proprioceptive afferents in humans. Experimental evidence in both human and animal has shown that the firing rate of Ia afferents was linearly correlated to joint angle. Yet, experiments did not elucidate how Ia encoding of joint angle would be affected by α−γ...
Packet classification is an important aspect of modern network systems. Packet classification systems have traditionally been built utilizing Ternary Content Addressable Memory (TCAM) due to the high throughput needed. However, TCAMs are expensive in terms of area and power consumption. An alternative to TCAM based systems using SRAM and a novel rule encoding method has been proposed to match multiple...
State-of-the-art hardware based techniques achieve high performance and maximize efficiency of packet classification applications. The predominant example of these, ternary content addressable memory (TCAM) based packet classification systems can achieve much higher throughput than software-based techniques. However, they suffer from high power consumption due to the highly parallel architecture and...
According to the system requirements, the multicarrier OFDM transmission scheme was proposed in intra-flight data link (IFDL) physical layer. Considering the anti-jamming vulnerability, the reliabilities of OFDM system were quantitatively analyzed under several burst interference. Combined with the convolution interleaving, (255,223)RS-(2,1,7) convolution concatenated coding that was proposed originally...
