Course Code: DS-MS-303
The course aims at a comprehensive presentation of the analysis and design of existing and new wireless communication networks. The area of wireless communication is one of the most dynamic areas in the communication field. The course covers the wireless channel characteristics and the transmission and reception techniques developed to cope with the channel impairments. Next, the design techniques of wireless systems are discussed and case studies are examined. Indeed, the characteristics and the fundamentals of existing systems (2G, 3G and 4G) are provided and a flavor of open research topics is given.
- Categories of wireless communications networks. Coverage, services and performance requirements of wireless networks. Network examples. Duplexing techniques, multiple access techniques and random access. Fundamentals of cellular network design.
- Propagation environment, mechanisms and propagation phenomena. Fading, types of fading, delay spread and intersymbol interference. Doppler spread and time variance.
- Analytic and empirical propagation channel models for outdoor and indoor environments. Shadowing and lognormal distribution. Calculation of coverage range and percentage. Empirical calculation of model parameters.
- Wideband channel characteristics. Flat, frequency selective and WSSUS channels. Characterization parameters (coherence bandwidth, coherence time, etc.). Fading mitigation techniques (diversity, OFDM, interleaving).
- Narrowband channels and characterization parameters. Scattering models and Rayleigh or Ricean fading.
- Diversity techniques (space and time). From SISO to SIMO and MISO systems. The advantages for the next generation systems.
- Spatial multiplexing techniques. From SISO to MIMO systems. Capacity and performance gains. The advantages for the next generation systems.
