Gray Coded 8-PSK Demo
Gray coding is a technique often used in multilevel modulation schemes to minimize the bit error rate by ordering modulation symbols so that the binary representations of adjacent symbols differ by only one bit. This demo simulates a communications link using Gray-coded 8-PSK modulation.
The sections that follow discuss the execution of the model and the variables used in the model. The section Learning More About the Gray Coding Demo discusses some ways you can modify the model and compare its results with theoretical values.
