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...

Adaptive Modulation and Coding (AMC) is combined with Multiple Input Multiple Output (MIMO) multiplexing to improve the throughput performance of AMC. In addition, Selection Transmit Diversity (STD) is considered in MIMO multiplexing to achieve higher diversity gain. AMC-STD-MIMO multiplexing system is proposed. STD in our simulation selects 2 transmission antennas from 4 antennas and AMC-MIMO ...

Abstract— Spatial multiplexing and diversity are in a tradeoff relationship. Multiple-input multiple-output (MIMO) can increase the maximum throughput in a good propagation environment by selecting high multiplexing order, but the achievable throughput degrades in a poor propagation environment. By adaptively selecting the multiplexing order according to the changing propagation environment, th...

Recent research on statistical multiplexing has provided many new insights into the achievable multiplexing gain in QoS networks, however, generally only in terms of the gain experienced at a single switch. Evaluating the statistical multiplexing gain in a general network remains a difficult challenge. In this paper we describe two distinct network designs for statistical end-to-end delay guara...

Wireless links with multi-antenna transmitters and receivers can be used to provide increased diversity and/or large data-rates. It has been shown that multi-antenna communication systems can simultaneously achieve the maximum diversity and maximum rate (or multiplexing) gain. This paper proposes a modified version of traditional spatial multiplexing that allows the wireless system to obtain ma...
