Bypassing the potentially excessive-complexity and yet inaccurate channel estimation, differentially encoded modulation in conjunction with low-complexity non-coherent detection constitutes a viable candidate for future multiple-antenna aided systems, where estimating all the links may become unrealistic, especially in high-speed environments. Upon exploiting the correlation between the phase distortions...
This paper proposes a video streaming mechanism with packet recovery which extends the Enhanced Adaptive Forward Error Correction (EAFEC) scheme by involving Multiple Description Coding (MDC) with path diversity. The proposed mechanism transmits multiple video sub-streams along multiple disjoint paths, then recovers the sub-streams using EAFEC separately, and at last merges and reconstructs the whole...
We present muNet, a wireless mesh network design and implementation to harness the multiuser capacity of wireless channels. Traditionally, media access control is designed to schedule one transmission between one sender and one receiver without interference at any given time. However, this design is suboptimal in terms of achieving the multiuser capacity of multi-access wireless channels. In muNet,...
Complex position code parallel combinatory spread spectrum (CPC/PC/SS) communication system with forward error correction (FEC) coding scheme is proposed in this paper, and performances are analyzed. CPC/PC/SS system with FEC coding scheme can be designed to have higher data transmission capability, even several times compared to ordinary PC/SS system on Gaussian channel.The proposed FEC coding is...
A major barrier for the adoption of wireless mesh networks is severe limits on throughput. Many in-network packet mixing techniques at the network layer [1], [2], [3] as well as the physical layer [4], [5], [6] have been shown to substantially improve throughput. However, the optimal mixing algorithm that maximizes throughput is still unknown. In this paper, we propose iPack, an algorithm for in-network...
