It is now well known that employing channel adaptive signaling in wireless communication
systems can yield large improvements in almost any performance metric. Unfortunately …

TDD (Time Division Duplex) is one of the two duplex modes. TD-SCDMA (Time Division
Synchronous CDMA) is the first TDD-based cellular mobile system which is commercialized …

MIMO-OFDM is a key technology for next-generation cellular communications (3GPP-LTE,
Mobile WiMAX, IMT-Advanced) as well as wireless LAN (IEEE 802.11 a, IEEE 802.11 n) …

Multiple-input multiple-output (MIMO) technology constitutes a breakthrough in the design of
wireless communications systems, and is already at the core of several wireless standards …

Multiple-input multiple-output (MIMO) wireless systems use antenna arrays at both the
transmitter and receiver to provide communication links with substantial diversity and …

This article provides a tutorial of linear precoding for a frequency-flat, single-user MIMO
wireless system, examining both theoretical foundations and practical issues. The article first …

Uniquely, this book proposes robust space-time code designs for real-world wireless
channels. Through a unified framework, it emphasizes how propagation mechanisms such …

Feedback in a communications system can enable the transmitter to exploit channel
conditions and avoid interference. In the case of a multiple-input multiple-output channel …

This paper deals with beamforming in wireless relay networks with perfect channel
information at the relays, receiver, and transmitter if there is a direct link between the …

Canonical labelling of graphs (CL, for short) can be used, eg, to test isomorphism. We prove
that a simple vertex classification procedure results after only two refinement steps in a CL of …
