ECE 4273 - Introduction to Mobile Communications - Fall 2022

Course Description:

This course will cover the physical-layer design issues in wireless "mobile" communication systems. The major topics covered are: characterization of the multipath propagation channel; digital modulation techniques over wireless "mobile" channels; diversity reception, including the linear combining and channel equalization; multiple antennas (MIMO) and space-time communications; basic concepts of cellular and IoT communications, such as cell splitting and frequency reuse; FDMA, TDMA, CDMA/WCDMA, and OFDM/OFDMA multiple access and massive connection techniques for spectrum sharing among users and devices; UAV/drone based communications for 3D cell coverage towards 5G and beyond.


Digital communications, probability and random process are the required prerequisites for this course. You will also be expected to be able to program in MATLAB.

The final exam will be taken in class (21534) from 15:00 to 18:00 on Wednesday, December 7. You will be allowed to bring one sheet of notes (both sides fine) into the exam along with calculators.

The following topics will be tested in your final exam:
1) Wireless mobile channels (path loss/shadowing/multipath, delay spread-coherence bandwidth/Doppler spread-coherence time)
2) Diversity schemes (across frequency, time, space), ISI/MIMO
3) Multiple access and interference management in cellular systems
4) Uplink vs. downlink user capacity
5) Capacity of wireless channels (slow vs. fast fading)
6) Multiuser diversity and opportunistic communication

The pre-recorded last lecture (at the end) on 14th week will briefly outline the type of questions and give some tips for the final exam.

Please review the assignments 1 to 4 and practice the old final exam posted on the 'Handouts' section.
