massive mimo system in matlab

You can create a Massive MIMO system in MATLAB by simulating a large number of antennas at the base station and multiple users. Here is a simple example to illustrate how you can create a Massive MIMO system in MATLAB:

main.m
% Define the parameters
num_antennas = 64; % number of antennas at the base station
num_users = 8; % number of users
num_symbols = 1000; % number of symbols to transmit

% Generate random data symbols
data_symbols = randi([0, 1], num_antennas, num_symbols);

% Generate random channel gains
channel_gains = (randn(num_antennas, num_users) + 1i*randn(num_antennas, num_users)) ./ sqrt(2);

% Perform MIMO processing (transmit data_symbols over the channel with channel_gains)
received_symbols = channel_gains * data_symbols; 

% Display the received symbols
disp(received_symbols);

In this example, we simulate a Massive MIMO system with 64 antennas at the base station, 8 users, and 1000 symbols to transmit. We generate random data symbols, random channel gains, and then perform MIMO processing by multiplying the channel gains with the data symbols. Finally, we display the received symbols.

This is a simple illustration of a Massive MIMO system in MATLAB. You can further extend and customize this code based on your specific requirements and scenarios.
