In low signal-to-noise ratio (SNR) scenarios, image wireless transmission is often interrupted due to the "threshold effect" in traditional digital communication system. Fortunately, it can be avoided in analog communication system, owing to its feature of linear degradation to noise. And to design the efficient analog error correction codes is the key to achieve high fidelity image. Considering...
The Delay/Disruption Tolerant Network (DTN) is characterized with intermittently connectivity and frequent partitions. Due to this, the DTN routing algorithm is very vulnerable to various kinds of malicious attacks. In this paper, combined with many other DTN forwarding approaches, we propose a multi-stage routing forwarding algorithm so as to further improve network throughput. To ensure the security...
Non-continuous orthogonal frequency division multiplexing (NC-OFDM) is an effective data transmission technology in cognitive radio (CR) system with high frequency efficiency and anti selective channel fading property. But as with OFDM systems, NC-OFDM also owns large side lobe power and high peak-to-average power ratio (PAPR), which leads to spectrum leakage of licensed users (LUs) and distortion...
