Simulation code: The repository also contains the code package that is distributed along with the textbook. The package contains a simulation environment, based on Matlab, that can be used to reproduce all the simulation results in the monograph. We hope that the code will support you in the learning of the Massive MIMO topic and also serve as a baseline for further research endeavors. We encourage you to also perform reproducible research!
Abstract of the Book
Massive multiple-input multiple-output (MIMO) is one of the most promising technologies for the next generation of wireless communication networks because it has the potential to provide game-changing improvements in spectral efficiency (SE) and energy efficiency (EE). This monograph summarizes many years of research insights in a clear and self-contained way and provides the reader with the necessary knowledge and mathematical tools to carry out independent research in this area. Starting from a rigorous definition of Massive MIMO, the monograph covers the important aspects of channel estimation, SE, EE, hardware efficiency (HE), and various practical deployment considerations.
From the beginning, a very general, yet tractable, canonical system model with spatial channel correlation is introduced. This model is used to realistically assess the SE and EE, and is later extended to also include the impact of hardware impairments. Owing to this rigorous modeling approach, a lot of classic “wisdom” about Massive MIMO, based on too simplistic system models, is shown to be questionable.
The monograph contains many numerical examples, which can be reproduced using Matlab code that is available online.
Content of the Code Package
This code package contains 74 Matlab scripts, 29 Matlab functions, and 7 binary files with Matlab data.
Each script is used to reproduce a particular simulation-generated figure in the book. The scripts are named using the convention sectionX_figureY, which is interpreted as the script that reproduces Figure X.Y. A few scripts are instead named as sectionX_figureY_Z and will then generate both Figure X.Y and Figure X.Z.
The functions are used by the scripts to carry out certain tasks, such as initiating a simulation setup, generating channel correlation matrices, generating channel realizations, computing channel estimates, computing SEs, computing the power consumption, etc.
The Matlab data files are of the type .mat and contain measurement results or particular precomputed simulation results.
Software and Hardware Requirements
The code was written to be used in Matlab and has been tested in Matlab 2015b. Some of the scripts and functions might also work in Octave, but there is no guarantee of compatibility.
A few scripts and functions require additional software packages that have been developed independently and are delivered with separate licenses. To generate Figures 7.2, 7.41, and 7.42, you need to solve convex optimization problems using CVX from CVX Research, Inc. (http://cvxr.com/cvx/). The code has been tested with CVX 2.1 (Build 1112) using the solver Mosek (version 126.96.36.199). We discourage the use of the solvers SDPT3 and SeDuMi since these crashed during the test. To generate Figures 7.41 and 7.42, you also need to generate channels using the QuaDRiGa channel model from the Fraunhofer Heinrich Hertz Institute (http://www.quadriga-channel-model.de). The code has been tested with QuaDRiGa version 1.4.8-571.
Since the running example in this monograph considers a setup with 16 cells, 100 antennas per BS, and 10 UEs per cell, some of the simulations require a lot of RAM to store the channel correlation matrices and channel realizations. The code has been tested successfully on a MacBook Pro with 8 GB 1600 MHz DDR3 RAM and a 2.6 GHz Intel Core i5 processor, which should be viewed as a minimum requirement for using this code. Some of the simulations can take days to run, therefore we recommend that you first set nbrOfSetups = 1 to check how much time it takes for each realization of random UE location and shadow fading.
