Simulation Assignment 2 (1)

Simulation Assignment 2 Communication Theory 1 April 9, 2019 Deadline:20/04/2019 Submission Format: • Submit single .zip file with roll-number as filename. • .zip file should contain a folder having .m files (simulation) and a PDF with analytical results. PDF of analytical results can be done either in Latex/Word or can write on A4 papers and take pics of it and put in one PDF file. • Make sure code is readable by providing proper indentation and comments wherever necessary. • Copying code from other students or from online will lead to no marks. • Expected Output: code upon running should produce SER/BER plots containing simulated and as well analytical for each question.

Questions 1. Derive the expression for Bit Error √ Rate√(BER) and Symbol Error Rate (SER) for QAM with square constellation (x = ± Eb ± j Eb ). 2. Derive the√expression for Symbol Error Rate (SER) with rectangular constellation (x = √ ± Eb ± j 3Eb ). 3. Perform MATLAB simulation to generate Symbol Error Rate (SER) Vs SNR per bit (Eb/N0) curve for Q1 and Q2 and verify whether theoretical results derived are consistent with simulation results.

Note: For Q3, vary noise power for (Eb/N0) while keeping average constellation energy constant. Also, assume that noise is additive in nature.
