LA UKkNCE E. MILSTEI>V is aprofessor with the Department ofElecmncal and Computer Engineering at the L’niwsily of California at San D q o . ver the past several years, code division multiple access (CDMA) has been shown to be a viable alternative to both frequency division multiple access (FDMA) and time division multiple acccss (TDMA), and the use of spread spectrum techniques (upon which CDMA...
متن کاملSpreading Codes for Wireless Spread Spectrum Communications
Spread spectrum techniques are often utilized when designing wireless communication systems. The success of a spread spectrum system depends greatly upon the spreading codes employed by the transmitters. In this paper, a novel approach to the generation of spreading codes is examined. In particular, spreading codes are generated as the impulse responses of a multirate subband lter bank. A metho...
متن کاملEfficient Wireless Communication System for Industrial Communications
IEEE 802.15.4 is a global standard designed for the low power consumption, low cost, and low data rate. Thus, this standard is advantageous to implement ubiquitous sensor network (USN). However, researchers do not have been studied to employ cooperative communication in this system. Cooperative relaying system has been shown to help the destination to get the spatial diversity. It is possible t...
متن کاملBandwidth-Efficient Wireless Multimedia Communications
Commencing with the brief history of mobile communications and the portrayal of the basic concept of wireless multimedia communications, the implications of Shannon’s theorems regarding joint source and channel coding for wireless communications are addressed. Following a brief introduction to speech, video, and graphical source coding as well as the cellular concept, a rudimentary overview of ...
