Getting Started

Setting Parameters in the BPSK Model

To set block parameters in the BPSK model, do the following:

1. Double-click the AWGN Channel block and set Es/No to 4.2.
2. Double-click the Error Rate Calculation block and make the following changes to the default parameters in the block's mask:
• Set Output data to Port.
• Check the box next to Stop simulation.

Running the BPSK Model

When you run the model, the Display block shows an error rate of approximately 0.01, the same as in the channel noise model. The BPSK model uses the BPSK Modulator Baseband, the AWGN Channel, and the BPSK Demodulator Baseband blocks to simulate a channel with noise. This provides a more realistic model of a channel than using just the Binary Symmetric Channel block. You can also model other types of channel noise using blocks from the Communications Blockset Channels library.
