I am trying to recover a signal by inverse Fourier-transforming the single-sided spectrum, but I am getting the wrong result. I do successfully transform the single-sided spectrum back to double-sided spectrum but from there I get lost. What am I doing wrong here? In fact, how can I recover the full information after doing abs(), isn't there lost info there?
Fs = 1000; % Sampling frequency
T = 1/Fs; % Sampling period
L = 1500; % Length of signal
t = (0:L-1)*T; % Time vector
S = 0.7*sin(2*pi*50*t) + sin(2*pi*120*t);
X = S + 2*randn(size(t));
figure(1)
plot(1000*t(1:50),X(1:50))
title("Signal Corrupted with Zero-Mean Random Noise")
xlabel("t (milliseconds)")
ylabel("X(t)")
Y = fft(X);
P2 = abs(Y/L);
P1 = P2(1:L/2+1);
P1(2:end-1) = 2*P1(2:end-1);
f = Fs*(0:(L/2))/L;
figure(2)
plot(f,P1)
title("Single-Sided Amplitude Spectrum of X(t)")
xlabel("f (Hz)")
ylabel("|P1(f)|")
X2=ifft(Y);
figure(3)
plot(X2(1:50))
Y2 = 2*[P1(1) P1(2:end)/2 fliplr(conj(P1(2:end)))/2];
X3 = ifft(L*Y2);

The problem appears (to me) that you are using the absolute value (‘P2’) of the fft result. This essentially discards the phase information.
If you also calculate the phase, for example using:
Q1 = angle(Y);
and then reconstitute it using:
Y2 = P1 * exp(1i*Q1);
you will likely get the original signal and can then take its inverse Fourier transform.
I included an example of this at the end after ‘Illustrating —’.
Fs = 1000; % Sampling frequency
T = 1/Fs; % Sampling period
L = 1500; % Length of signal
t = (0:L-1)*T; % Time vector
S = 0.7*sin(2*pi*50*t) + sin(2*pi*120*t);
X = S + 2*randn(size(t));
figure(1)
plot(1000*t(1:50),X(1:50))
title("Signal Corrupted with Zero-Mean Random Noise")
xlabel("t (milliseconds)")
ylabel("X(t)")
Y = fft(X);
P2 = abs(Y/L);
P1 = P2(1:L/2+1);
P1(2:end-1) = 2*P1(2:end-1);
f = Fs*(0:(L/2))/L;
figure(2)
plot(f,P1)

Thank you for looking into this but I actually want to recover the original signal exclusively from the single-sided spectrum, without knowing the original signal of course

My pleasure!
It will always be necessary to calculate the phase so that you can fully reconstitute the original signal. Add that and your code should work. Treat the phase values the same way you treat the magnitude values, with the appropriate sign change for the ‘second half’ of the reconstituted Fourier transform vector —
v = randn + 1i*randn;
vs = [v; conj(v)]
vs =
0.1080 + 1.0408i 0.1080 - 1.0408i
M = abs(vs)
M = 2x1
1.0464 1.0464
<mw-icon class=""></mw-icon>
<mw-icon class=""></mw-icon>
phi = angle(vs)
phi = 2x1
1.4674 -1.4674
<mw-icon class=""></mw-icon>
<mw-icon class=""></mw-icon>
Also note that you need to add the ‘symmetry flag’ to your ifft call. In this instance, use 'symmetric' because your signal has an even number of elements originally, so the fft result will also. (If you use the default 'asymmetric' your ifft result will have complex values.)
