采用卷积编码与维特比译码对通信过程进行了仿真，展示了卷积码的差错校正容量，调制方式采用QPSK-This demo shows how to use a convolutional encoder and decoder in a
simulation of a communications link. It also shows the error correcting capability of convolutional codes. This demonstrates the convolutional
trellis generator, POLY2TRELLIS, encoder, CONVENC, and decoder, VITDEC.
It also demonstrates the use of other functions (e.g. INTDUMP, RECTPULSE,
BITERR, BERCODING, RANDSRC, and AWGN) and objects (MODEM.PSKMOD and
MODEM.PSKDEMOD). Many of these functions are described in greater detail
in the "Phase Shift Keying Simulation" demo. Finally, this demo displays
empirical performance curves for QPSK with Gray coding using data
generated by the example, VITSIMEXAMPLE.
