Diversity-Multiplexing Tradeoff in MIMO Systems
نویسنده
چکیده
It is well known that there exists a tradeoff between the diversity gain and the multiplexing gain achievable by a particular MIMO coding scheme. In this report we first look at the optimal trade-off in the infinite signal-to-noise (SNR) regime of both Rayleigh independent and identically distributed (i.i.d.) channels and a more general MIMO channel model. We then look at the tradeoff of both Space-Time Block Codes (such as Alamouti code) and BLAST Detection schemes. The effect of non-identically distributed and correlated channels is also briefly discussed. Finally, the diversity multiplexing (DIV-MUX) tradeoff is presented under the finite SNR regime.

Diversity Versus Multiplexing in Narrowband MIMO Channels: A Tradeoff Based on Euclidean Distance
Multiple-input multiple-output (MIMO) communication systems use antenna arrays at both the transmitter and the receiver to offer substantial benefits in terms of rate and reliability. Two standard approaches for communicating in MIMO systems are spatial multiplexing and transmit diversity. Multiplexing sends independent information streams across the transmit antennas to maximize rate while tra...
متن کاملTransmit Diversity v. Spatial Multiplexing in Modern MIMO Systems
A contemporary perspective on the tradeoff between transmit antenna diversity and spatial multiplexing is provided. It is argued that, in the context of most modern wireless systems and for the operating points of interest, transmission techniques that utilize all available spatial degrees of freedom for multiplexing outperform techniques that explicitly sacrifice spatial multiplexing for diver...
متن کاملDiversity-Multiplexing Tradeoff
In this paper, we focus on the diversity-multiplexing tradeoff (DMT) in MIMO channels and introduce the development of DMT in MIMO channels. Zheng and Tse first proposed DMT in MIMO channels and based on their ideas, other researchers extended to many different aspects. We will study DMT in different MIMO fading channels, DMT curves and DMT under different protocols.

In this paper, we analyze the outage performance and diversity-multiplexing tradeoff (DMT), originally introduced by Zheng and Tse, for certain classes of multiple antenna systems. In particular, three types of practical channel models such as Rician model, rankdeficient model, and spatially correlated model are considered. The asymptotic behaviors of the outage are analyzed in the limit of hig...
متن کاملOptimal Diversity Vs Multiplexing Trad Mimo Channe
In this paper we derive the optimal diversity versus multiplexing tradeoff for a frequency selective i.i.d. Rayleigh MIMO channel. This tradeoff is shown to be better than the one of the frequency flat MIMO channel. Traditional approaches for frequency selective channels use OFDM techniques in order to exploit the diversity gain due to frequency selectivity. We show that although coding in OFDM...
