This module focuses on how received signals are demodulated with and without the channel state information and which kind of receiver performs well under different scenarios. You will also learn about the different channel assumptions, such as fixed channel, no channel information at the transmitter/receiver, slow-fading channel, and fast-fading channel.

This module will focus on ways to increase a cellular network’s overall throughput. The module analyses the spectral efficiency for different configurations of cellular networks, for example, single/multiple-antenna at the base station, single/multiple users in a cell, and two-cell/multiple-cell in a cellular network . You will gain insights into which network configuration best suits maximizing the area throughput. The impact of the increase in antenna/users/cells will be discussed in detail, with spectral efficiency as the metric. The module will consider different channel settings, such as line-of-sight and non-line-of-sight. Also, you will learn how antenna placement affects channel modeling.

This module will act as a bridge between multi-user MIMO and massive MIMO systems. The module will explain when a multi-user MIMO system can be called a massive MIMO system. You will learn about different properties of massive MIMO, for example, channel hardening and favorable propagation. You will learn why channel estimation is an important aspect, mainly when you consider a massive MIMO system. The focus will be on how to calculate an estimate of channels with limited overhead. Further, it will discuss different ways to estimate channels, such as the minimum mean square error (MMSE), least-square (LS), semi-blind, and superimposed channel estimation techniques.

In this module, you will learn the need to shift the operating frequency bands of the upcoming wireless systems towards the mmWave frequency bands. You will also learn the challenges involved in realizing such systems. Subsequently, you will learn to characterize the mmWave channel models, specifically the narrowband and wideband models. Later, you will be exposed to the key design consideration for modeling a mmWave system.

In this module, you will understand the role of beamforming in a wireless system. You will begin by learning the three beamforming architecture types: analog, digital, and hybrid. Subsequently, you will be exposed to modeling the uplink and downlink systems utilizing these beamforming architectures. Lastly, you will comprehend the beamforming objectives and learn a few selected algorithms for achieving the same.

In this module, you will learn how the channel property changes and causes an inter-symbol interference when we start realizing a wideband system, resulting in severe performance degradation. You will further learn how a multi-carrier modulated system can combat such degradation and pave the way for a widely accepted and commercialized technique known as “orthogonal-frequency division multiplexing (OFDM).” The module will discuss the OFDM system model and its performance characterization. Subsequently, the model will be extended for a multiple-input multiple-output (MIMO) system. You will also learn a few of the selected realization issues of the OFDM system.

In this module, you will learn how introducing an overlapping (i.e., a non-orthogonal) resource allocation can help in improving the overall throughput of the wireless system. The first part of the module will describe the basics of non-orthogonal multiple access (NOMA), considering a two-user scenario. The focus will be on developing an understanding of its transmitter and receiver structure and the constituent algorithms. Subsequently, the second part of the module will extend the idea to multi-user scenarios and multiple antenna cases. Lastly, this module will discuss a few of the other popular forms of NOMA.
