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...

The paper presents ultra-high-capacity transmission technologies based on multi-core space-division-multiplexing. In order to realize high-capacity multi-core fiber (MCF) transmission, investigation of low crosstalk fiber and connection technology is important, and high-density signal generation using multilevel modulation and crosstalk management are also key technologies. 1 Pb/s multi-core fi...

We previously proposed the Orthogonal Code Hopping Multiplexing(OCHM) scheme as a new statistical multiplexing scheme in synchronous downlink and applied the OCHM scheme to IS-95 and Wideband CDMA. OCHM enables a large number of users to share the limited number of code channels through statistical multiplexing. In this paper, we compare OCHM with HDR through link-level simulation. OCHM outperf...

This paper is motivated by the need to provide per session quality of service guarantees in fast packet-switched networks. We address the problem of characterizing and designing scheduling policies that are optimal in the sense of minimizing buuer and/or delay requirements under the assumption of commonly accepted traac constraints. We investigate buuer requirements under three typical memory a...

—Microsatellite multiplexing is a powerful technique that can increase the productivity of genetic studies in fisheries biology. We review multiplexing methods and present an optimized and detailed protocol for microsatellite multiplexing that is specifically tailored for use with radioisotopes. The protocol can significantly reduce the cost associated with microsatellites and provides high pol...

Two signal multiplexing strategies for multi-user optical fiber communication are considered: Wavelength-division multiplexing (WDM) and nonlinear frequency-division multiplexing (NFDM), based on the nonlinear Fourier transform (NFT). The inverse NFT is implemented using an approach that is dual of the forward NFT and does not require solving integral equations. In contrast to prior work where ...

Effective Bandwidth is a powerful tool in modeling bandwidth and buffer requirements for multiplexed data sources. It is often approximated that an additional service capacity equal to the effective bandwidth of the source is required for every additional data source added to the multiplexed stream given a fixed buffer size and maximum blocking probability. This implies that a multiplexing gain...

In this Letter we show that living cells can multiplex biochemical signals, i.e., transmit multiple signals through the same signaling pathway simultaneously, and yet respond to them very specifically. We demonstrate how two binary input signals can be encoded in the concentration of a common signaling protein, which is then decoded such that each of the two output signals provides reliable inf...
