Homework Statement
A signal x(t) is transmitted and received back as y(t) and sampled in the receiver, so we get a DT signal
y[n] = ax[n-D] + w[n], where w[n] is noise
baiscally i need to explain how we can measure the time delay by computing crosscorrelation Ryx(l).
My undestanding is:
cross-correlation measures how similar the signals are, so if we ccompute cross correlation of a signal with its reflected version, we will get shifted peaks, and the amount of shifting is the delay
Is this correct?
