书籍 The+Telecommunications+Handbook
Changes in telecommunications are impacting all types of user
group, which include business users, traveling users, small and
home offices, and residential users. The acceptance rate of telecom-
munications and information services is accelerating significantly.
Voice services needed approximately 5 ...
书籍 Time-Varying Channels
Wireless communications has become a field of enormous scientific and economic interest. Recent
success stories include 2G and 3G cellular voice and data services (e.g., GSM and UMTS), wireless
local area networks (WiFi/IEEE 802.11x), wireless broadband access (WiMAX/IEEE 802.16x), and
digital broad ...
书籍 UMTS+Network+Planning
The continuing explosive growth in mobile communication is demanding more spectrally
efficient radio access technologies than the prevalent second generation (2G) systems such as
GSM to handle just the voice traffic. We are already witnessing high levels of mobile
penetration exceeding 70% in some c ...
书籍 Utility Maximization in Nonconvex Wireless Systems
Once upon a time, cellular wireless networks provided two basic services: voice
telephony and low-rate text messaging. Users in the network were separated
by orthogonal multiple access schemes, and cells by generous frequency reuse
patterns [1]. Since then, the proliferation of wireless services, fi ...
书籍 VoIP+and+Unified+Communications
This book intends to prepare you to define Unified Communications (UC) for
yourself and then get it to work for you.
Each vendor pulls together from its available products a package of features
related to voice, data, messaging, and image communications. That’s UC for
one vendor, but it’s unlikely ...
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 ...
书籍 Wireless Communications & Networking
During the past three decades, the world has seen signifi cant changes in the telecom-
munications industry. There has been rapid growth in wireless communications, as
seen by large expansion in mobile systems. Wireless communications have moved
from fi rst-generation (1G) systems primarily focused ...
书籍 Wireless Networks Multiusers Detection
Wireless networking is undergoing a transformation from what has
been primarily a medium for supporting voice traffic between telephones,
into what is increasingly becoming a medium for supporting traffic among
a variety of digital devices transmitting media of many types (voice,
data, images, video ...
书籍 Wireless Receiver Architectures and Design
The advent of modern wireless devices, such as smart phones and MID 1 terminals,
has revolutionized the way people think of personal connectivity. Such devices
encompass multiple applications ranging from voice and video to high-speed data
transfer via wireless networks. The voracious appetite of tw ...
书籍 Foundations of MEMS
