Study of CDMA technique: Basic Concepts, Initial learning, CDMA technique - Tapa blanda

Sinopsis

Over the last three decades, the wireless communication technology is dominating over another technology. In this thesis, basic study of CDMA technique,is elaborated for the purpose of understanding & learning the initial concepts for the undergraduate engineering students and also those who are enthusiastic about CDMA technique. The Code Division Multiple Access (CDMA) is a digital cellular technology pioneered by QUALCOMM in USA in which signals are encoded using a pseudo-random sequence (PN sequence) - which corresponds to a different communication channels that the receiver also knows and can use to decode the received signal.CDMA provides much better and cost-effective voice quality, privacy, system capacity and flexibility than other wireless technologies, along with enhanced exciting new generation of wireless communications products and services such as short messaging, e-mail and Internet access.In this thesis paper, we include the following articles concerning CDMA technique such as classification, network structure, air interface, codes, voice conversion & call setup, power control, antenna array, handoff & receiver.
