5. Waveform Generation
   1. Generate zeros
      • zeros([M , N ]) – M by N matrix of zeros
        • zeros ([1, 400])
   2. Generate ones
      • ones([1, 240 ])
   3. Combine waveforms (concatenate arrays)
      • cat( DIM, A, B)
        • Example: cat (2, y1, y2)
   4. Make a waveform into complex format
      • a = hilbert(y)
      • I_channel = real(a)
      • Q_channel = imag(a)
