Compute BER for QAM System with AWGN Using MATLAB

Communications Toolbox™ features build upon the MATLAB^® computational and visualization tools, enabling you to use higher level functions when simulating communications systems. This set of examples shows how to compute the bit error rate (BER) on a 16-QAM signal distorted by an AWGN channel.

• Examine 16-QAM Using MATLAB — Shows a basic 16-QAM communications link

• Use Pulse Shaping on 16-QAM Signal — Extends the basic 16-QAM communications link example to include pulse shape filtering

• Use Forward Error Correction on 16-QAM Signal — Extends the 16-QAM communications link with pulse shaping example to include forward error correction (FEC)
