The class advanced wireless communications offers a description of relevant techniques for data transmission in wireless channels. It starts with a review of basic topics in mobile communications (as the cellular concept, fading channel models, digital modulation techniques). Then, it discusses the performance in fading channels of digital modulation, antenna diversity techniques, state-of-the-art multicarrier modulation techniques, spread spectrum and code division multiple access, ultra wide band modulation. It also considers radio systems for localization and positioning such as the Global Positioning System (GPS) and terrestrial radio localization systems.Review of the cellular communication conceptMobile wireless channel: channel impulse and frequency response, slow and fast fading and its statisticsBaseband representation of a digital modulation systemPerformance analysis of digital modulation in fading channelsSignal-to-noise ratio distribution, average probability of error in Rayleigh fadingAntenna diversity techniques and performance: selection combining and maximal ratio combiningPrinciple of multiple-input multiple-output transmission and effect on system capacityMulticarrier modulation: OFDM and Filtered Multitone Modulation techniques. Spread spectrum systems: DS-CDMA, multiple access interference, rake receiverUltra wide band modulationPrinciples of radio localization, triangulation and trilaterationSome elements of wireless standards

Students are expected to have some preliminary knowledge on:digital communication systemssignal theory and representation of linear systemselements of probability, random variables and random processes. Depending on students background, complementary preliminary content will be provided to make sure the class is self-contained.
