书籍 Compressive+Sensing+for+Wireless+Networks
Over the past few decades, wireless communications and networking have witnessed an
unprecedented growth, and have become pervasive much sooner than anyone could have
predicted. For example, cellular wireless networks are expected to become the dominant
and ubiquitous telecommunication means in the ...
书籍 Protocol Engineering
Communication protocols – for short protocols – form the basis for the opera-
tion of computer networks and telecommunication systems. They are behavior
conventions which describe how communication systems interact with each other
in computer networks. Protocols define the temporal order of the in ...
书籍 WCDMA for UMTS HSPA Evolution and LTE
Second-generation telecommunication systems, such as the Global System for Mobile
Communications (GSM), enabled voice traffic to go wireless: the number of mobile phones
exceeds the number of landline phones and the mobile phone penetration is approaching
100% in several markets. The data-handling c ...
