EE 652 - Wireless & Cellular Telecommunication

3 Credit(s)

Topics include mobile and fixed wireless systems—cellular and point-to-point technologies. Wireless LANs, wireless STM (synchronous transfer mode), wireless cable, wireless local loops, microwave and satellite systems, cordless telephones, PCS (personal com mu nication systems), and multimedia and video mobile services. Cellular concepts for macro-, micro-, and picocellular networks; frequency reuse, hand-offs, channel interference. Radio propagation effects of reflection, diffraction and scattering; use of microwave, millimeter, and optical infrared frequencies; climactic effects, directional and multiple antennas. Large-scale propagation models of path loss in irregular terrain, urban areas, microcells, and buildings. Small-scale models of fading, time-delay spread, and Doppler spread due to multipaths, movement of transmitter/receivers, or of surrounding objects and transmission bandwidth; statistical models of fading. Digital modulation—QAM (quadrature amplitude modulation), MSK (minimum shift keying), Gaussian MSK, spread spectrum, adaptive and multicarrier modulation. Signal processing to improve quality; adaptive equalization, diversity techniques, block and convolutional coding, trellis-coded modulation. Access methods—time, frequency, and space-division, frequency hopping and code division, and random access packet radio. inter-networking, signaling, and national and international standards.
