TL;DR: This article highlights some of the recent information theoretic limits, models, and design of these promising networks of intelligent, adaptive wireless devices called cognitive radios.

TL;DR: This article provides a tutorial of linear precoding for a frequency- flat, single-user MIMO wireless system, examining both theoretical foundations and practical issues.

TL;DR: Borders on the primary exclusive radius RO and the guard band isinp are determined to guarantee an outage performance for the primary user, even with an arbitrarily large number of cognitive users uniformly distributed with constant density outside the primaryexclusive region.

TL;DR: This paper proposes linear precoder designs exploiting statistical channel knowledge at the transmitter in a multiple-input multiple-output (MIMO) wireless system, using a convex optimization framework to minimize the Chernoff bound on the pairwise error probability (PEP) between a pair of block codewords.

TL;DR: In closed-form, the capacity and the optimal signaling scheme for a MISO channel with per-antenna power constraint are established and two cases of channel state information are considered: constant channel known at both the transmitter and receiver, and Rayleigh fading channel known only at the receiver.
