Diversity-multiplexing tradeoff in mode-division multiplexing.
The capacity of mode-division multiplexing (MDM) systems is limited, for a given outage probability, by mode-dependent loss (MDL) and gain. Modal degrees of freedom may be exploited to increase transmission rate (multiplexing gain) or lower outage probability (diversity gain), but there is a fundamental tradeoff between the achievable multiplexing and diversity gains. In this Letter, we present...
متن کاملPolytopic multiplexing.
Polytopic multiplexing is a new method of overlapping holograms that, when combined with other multiplexing techniques, can increase the capacity of a volume holographic data storage system by more than a factor of 10. This is because the method makes possible the effective utilization of thick media. An experimental demonstration of this technique is also presented.
متن کاملStatistical Multiplexing
Twenty-first century communications will be dominated by intelligent high-speed information networks. Ubiquitous access to the network through wired and wireless technology, adaptable network systems, and broadband transmission capacities will enable networks to integrate and transmit media-rich services within specified standards of delivery. This vision has driven the standardization and evol...
متن کاملOrthogonal Code Hopping Multiplexing for Downlink Statistical Multiplexing
For orthogonal downlink and statistical multiplexing, three modes of orthogonal code hopping multiplexing (OCHM) are proposed to accommodate more orthogonal downlink channels than orthogonal codewords for downlink channels, and they are compared. The performance comparison shows that the hybrid mode OCHM outperforms both the division mode and the hopping mode.
متن کاملDiversity-Multiplexing Tradeoff
In this report, we study the diversity-multiplexing tradeoff(DMT) in MIMO channels. DMT in MIMO channels is first introduced by Zheng and Tse. Based on their ideas, other researchers extended to different aspects. We will study DMT in two different aspects. In the first aspect, we will introduce DMT in different MIMO fading channels. In the second aspect, we will study different codes which wil...
