Evolution of Air Interface towards 5G

This learning track covers the comprehensive evolution of wireless communication systems, from the first generation to the current fifth generation, and beyond. It provides an in-depth understanding of the development cycle of communication standards, the ITU-R recommendations, and a summary of GSM and IMT-2000. The track also delves into the technical aspects of these systems, including their bandwidth, chip rate, frame length, modulation, and channel coding. It concludes with a detailed discussion on the requirements and performance of IMT-Advanced or 4G systems, cell spectral efficiency, and the transition from 4G to 5G. The learning track further explores the intricacies of 5G technology, its requirements, operating scenarios, and design aspects. It also covers the comprehensive study of waveform analysis and multi-dimensional signaling, waveform design in telecommunication, 5G numerology and frame structure, waveforms beyond 5G communication, channel models for performance evaluation, and MIMO signal processing techniques.
