create a function that generates a binary offset carrier wave modulation in matlab

main.m
function [modulated_signal] = gen_boc_modulation(bits, fc, fd, Fs)
% Generates a binary offset carrier wave modulation
% bits: sequence of binary data, 1s and 0s
% fc: carrier frequency
% fd: data frequency
% Fs: sampling frequency
% modulated_signal: the modulated signal

t = 0 : 1/Fs : length(bits)/fd;
boc_signal = sign(cos(2*pi*fc*t) + bits.*cos(2*pi*(fc-fd)*t));
modulated_signal = (boc_signal + 1)/2;
