Lab 1 - Conclusion

Edit me

In this lab, you:

• used GNU Radio to build a baseband communication system,
• made a histogram of the noisy received bits and related that the the bit error values,
• recorded BER values for several \(\sigma\) values,
• wrote a short script to turn them into \(BER versus \sigma\) and \(BER versus \frac{a_1-a_2}{2\sigma}\) curve.

Deliverables

In this lab there are the following deliverables:

• a single page of answers to the deliverable questions laid out in the lab. In this lab there are 4 of them. They are all highlighted and labelled with their respective question numbers. Each question (hopefully) required some thought and was answered concisely with 1 to 2 sentences of text and perhaps an accompanying figure,
• a short code you wrote to generate the BER curves curves,
• your final BER curve figures.

Submit these three deliverables to your TA over coursespaces.

Optional

Repeat the experiment where \(P(s_1) \neq 0.5\) and find the threshold value that yields the minimum BER (see Sklar problem 3.6).
