This course will cover basic principles in the design of mobile communication systems, included in the various generations of cellular systems from 1G to 5G. The radio propagation environment: basic radio propagation considerations, Rayleigh and Rician statistics, power spectral density, small scale and large scale signal variation, delay spread, Doppler spread, and angular spread, coherence bandwidth, coherence time, and coherence space; MIMO channel modeling. Link issues: modulation techniques including OFDM, diversity, interleaving, forward error correction. Principles of spread spectrum systems and CDMA. System issues: spectral sharing schemes, frequency re-use, noise, and interference analysis, call and packet oriented capacity analysis, and basic scheduling approches including proportional fair. Drop oriented network simulation models. Basic aspects of cellular system standards such as GSM, WCDMA, LTE, and 5G new radio. Familiarization with software radio architecture of commercially available systems including RF chip architecture, FPGA and host processing. RF bands covered, local oscillator management and phase lock, RF filtering, down-coversion, IQ sampling, and digital filtering, frequency and phase synchronization, and demodulation. Issues in the implementation of antenna arrays and massive MIMO. The course will have various exercises based on software radio and matlab including the analysis of real off-the air cellular system pilot and synchronization signals.
