Introduction - If you have any usage issues, please Google them yourself
Matlab gaussian channel conditions using QPSK and eight PSK point to point communication system theory and statistical the error rate and bit error rate curve.
Delete the convolution code more than Pb performance simulation
Join channel coding module, draw bit error rate curve, which channel to additive gaussian white noise, commissioning for QPSK
In the soft decision and judgment should be, and with more than 3/4, 7/8 delete code for coding, etc.
