Abstract

The course will go through advanced topics in wireless such as massive MIMO, cognitive radio and other related topics as described below.

For realization of IoT by 2020, wireless physical layer has been considered as an essential unifying fabric that will connect billions of devices. In comparison to the current generation (4G) wireless, next generation wireless networks are expected to have 1000 fold improvement in system throughput, 10 times spectral efficiency, higher data rates (i.e., the peak data rate of 10 Gb/s and the user experienced rate of 1Gb/s), 25 times average cell throughput, 5 times reduction in End-to-End (E2E) latency and 100 times higher connectivity density. Research is needed to understand how these next generation wireless networks integrate and enable wireless IoT systems and how they can be exploited to enable a multitude of application domains such as security, cloud networks, biomedical, smart grid and others. Wireless connectivity is essential for deployment of massive numbers of nodes with heterogeneous service requirements. Emerging wireless technologies such as Massive multi- input-multi-output (MIMO), millimeter wave (utilizing 30GHz – 300GHz frequencies), and full-duplex will soon change the landscape of wireless technology. To this end, research is needed on developing new theories and technologies tailored for realistic path loss, signal blockage, and antenna gain patterns suitable for millimeter wave and massive MIMO systems. Moreover, viable power control and receiver association techniques will be needed.

Due to the massive growth of wireless applications and users globally, the prime radio spectrum has already been fully licensed, leading to potential spectrum scarcity. However, licensed users or primary users (PUs) at many locations temporarily leave their spectrum slots unused. These temporarily unused spectrum bands (a.k.a., spectrum holes) may be accessed by unlicensed or secondary users (SUs), which will clearly improve the overall spectrum usage or equivalently the spectral efficiency. That is the motivation behind the development of cognitive radio (CR). CR nodes are designed to sense the environment, detect spectrum holes and access them dynamically. Therefore, the error-free detection of spectrum holes limits the potential interference on PUs and improves the overall spectral efficiency.

Specifically, the course content is divided into five sections:

1. The wireless channel, time and frequency coherence, statistical channel models,

2. Wireless performance analysis fundamentals,

3. Multiple-input, Multiple-output (MIMO) wireless systems,

4. Relay networks,

5. Cognitive radio fundamentals.

 

Textbooks: Wireless Communications, Andreas F. Molisch; Wiley - 2 edition (December 1, 2010) and

Fundamentals of Wireless communications, Tse and Viswanath.

Prerequisites: Students require a solid background on digital communications and probability as well as

linear algebra and MATLAB programming. Those who are without these prerequisites should consult the

instructor and if they proceed to take this course, they are expected to fill in the background material on

their own.
