关于此课程： This course will provide an introduction and history of cellular communication systems that have changed our lives during the recent four decades and will become an essential and inseparable part of human life. The principles of wireless communication theory are covered with emphasis on the essential concept delivery to non-major learners in the easiest way. Then, it will be covered how such principles are realized and how multimedia services can be delivered in practical LTE cellular systems by which learners are connected and enjoys together in their lives. After completing this course, learners will be able to understand 1. What a cellular system is and how it has been developed so far 2. The very basic principles how information can be delivered efficiently using radio 3. How such principles are realized in LTE systems. 4. How people can be connected and multimedia services can be delivered in LTE systems
此课程适用人群： Learners who have general interest in information & communication technology (ICT)

Principles of Wireless Communication Theory
In this part of the course, we will learn the fundamental principles of wireless communication theory. I will raise five fundamental questions in the first lecture as follows: i) 'how can we represent information into a binary format?', ii) 'how can information be transferred?', iii) 'how does wireless digital MODEM work?', iv) 'how can high-rate data be delivered reliably?', and v) 'how can many users access simultaneously?'. During the following 5 lectures, you will have the answers.

Multiple Antenna Technologies
In this part of the course, we will learn how multiple antennas can be efficiently used in different strategies for communication system enhancement. First, we look in to the basics of antenna, and then learn about the three main gains that are achievable by multiple antennas: array, diversity, and spatial multiplexing. Lastly, we briefly look in to the concepts of single-user MIMO and multi-user MIMO.

评分和审阅
The Content was excellent but some parts were a bit hard to understand.
En algunas ocasiones no queda muy claro los conceptos que se quieren dar a comprender. O algunos términos usados. No hacen la referencia en el momento, sino hasta después. Pero en general, me pareció un curso con alto contenido conceptual para el entendimiento básico del funcionamiento de la red celular. Lo cual ahora comprendo muchos términos usados comúnmente en este campo.
Excellent course, for LTE and wireless communication
Excelente curso, realmente fue lo que esperaba, incluso mejor aunque hubiese sido bueno que dieran una capitulo al diseño de antenas
