This special issue aims to collect cutting-edge research achievements in this area. We solicited papers that present original and unpublished work on topics including, but not limited to, the following: physical layer models, for example, channel mo
Cognitive radio is widely expected to be the next Big Bang in wireless communications. Spectrum sensing, that is, detecting the presence of the primary users in a licensed spectrum, is a fundamental problem for cognitive radio. As a result, spectrum
阐述很详细，适合研究生。 Abstract—In Multi-User MIMO networks, receivers decode multiple concurrent signals using Successive Interference Cancellation (SIC). With SIC a weak target signal can be deciphered in the presence of stronger interfering signals. Howeve
In this paper we present an architecture for Software Defined Cognitive Radio that caters to the specific baseband processing requirements in a changing environment. We aim to provide more flexibility by de-constructing the radio pipeline into a fra
In this article we discuss the different multiple antenna techniques introduced in LTEAdvanced. Rather than describing the technical details of the adopted solutions, we approach the problem starting from the design targets and the antenna deploymen
This paper presents a HACE theorem that characterizes the features of the Big Data revolution, and proposes a Big Data processing model, from the data mining perspective. This data-driven model involves demand-driven aggregation of information sourc
