Radio Communications Foundation is written by Tse, a new generation of authority in the field of wireless communications. It has been used as a textbook by many famous universities such as UC Berkeley, MIT and Qualcomm. Radio Communications Foundation focuses on the basic principles of wireless communications. Readers need only have the basic background of probability theory and digital communications. The main issues covered in the Radio Communication Foundation are MIMO communication, space-time coding, opportunistic communication, OFDM and CDMA, which are illustrated by a large number of examples of wireless systems. The fundamentals of wireless communications emphasize the interaction between concepts and their implementation in systems. The book is also equipped with a large number of exercises and charts, which can help readers further understand the contents of the material. (2018-10-10, Others, 5866KB, 下载2次)
