                                 Labs

Lab 1 (4)

- a plot of amplitude vs time
- a histogram of the amplitude and a fit Rayleigh
- a log-log plot of path loss vs distance
- a path loss exponent that matches the curve above

Lab 2 (6)

- GUI captures showing the four test cases (4)
  - center frequency of 222.5
  - frequency shifted to 223.5
  - longer period (narrower spacing of harmonics)
  - disabling interpolator filter (replicated spectrum)
- answers to questions (2)
  - result is sinusoid at sum of frequencies
  - period is fs/2^N

Lab 3 (6)

- two GRC flowgraphs (2)
- screen capture
- spreadsheet with correct Eb/No and BER
- plot showing BER with/without FEC
- correct calculation of coding gains

Lab 4 (2)

- reasonable code
- screen capture
(completion mark was based on demonstration in the lab)

Lab 5 (3)

- screen capture
- four spectra (N=128, nc=32, fs=1e6; N=>256; nc=>64; fs=>2 MHz)
- three reasonable explanations of how the spectra changed
  the bandwidths should be:
  1: 32/128 * 1 MHz = 250 kHz
  2: 32/256 * 1 MHz = 125 kHz
  3: 64/128 * 1 MHz = 500 kHz
  4: 32/128 * 2 MHz = 500 kHz
