ECE 561 – Digital Communications Systems MATLAB Assignment #3 Part 1. Create a Simulink model similar to the one described in MATLAB Tutorial #3 to generate and detect 1Kbps information represented by the unipolar binary signal set: s 1 ( t ) = 1; 0 t 1 ms represents a “1”, and s 2 ( t ) = 0; 0 t 1 ms represents a “0”. Consider/include the following: The system sampling rate should be 50 µ s Use a correlation receiver Remember that the asymmetrical signal set will have a non-zero threshold voltage. This can be implemented by adding the appropriate constant to the output of the integrator before the Sign block. Include a Error Rate Calculation block and display. Use the AWGN channel. Remember that the input signal power input in this block is the

Unformatted text preview: average of the power in s 1 and s 2 . Set the AWGN channel to output no noise power (variance = 0) and run the simulation for 20ms. Printout and compare the original data stream with the detected output. Confirm that the pulses are detected correctly. Part 2. Run the simulation for 10,000 bits and record the bit error probability for E b /N o in dB of 0, 2, 4, 6, 8, and 10. Part 3. Using the theoretical bit error probability for this system derived in class, plot the theoretical bit error probability curve versus E b /N o (in dB). Let E b /N o range from 0 to 10 dB. Plot the simulated results (as red asterisks) along with this curve. How does your simulation compare to the theoretical values?...
