Questions and Answers

What is the purpose of the 'mup' variable in the given MATLAB code?

  • To filter the input signal using a blip pulse
  • To oversample the input signal by an integer factor (correct)
  • To modulate the input signal with a carrier signal
  • To create a pulse shaped received signal

What does the 'ps=hamming(M)' line of code achieve in the given MATLAB script?

  • It constructs the carrier signal
  • It modulates the input signal with a carrier signal
