Description: 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.

Description: BPSK与模拟通信系统相比，数字调制和解调同样是通过某种；在大多数情况下，数字调制是利用数字信号的离散值去；三种数字调制方式在抗干扰噪声能力和信号频谱利用率；2BPSK调制原理；二进制相移键控（BPSK）是利用基于MATLAB中的BPSK误码性能研究；
MATLAB提供了卷积码的convenc和相应的Viterbi译码函数vitdec，可以快速地得到编译码的结果。(BPSK compared with the analog communication system, digital modulation and demodulation is also through some; in most cases, digital modulation is discretized using the digital signal value; three kinds of digital modulation in the utilization of anti noise ability and signal spectrum principle; 2BPSK modulation; two for phase shift keying (BPSK) is the use of study on the BER performance of MATLAB based on BPSK;
MATLAB provides convolutional code convenc and the corresponding Viterbi decoding function vitdec, which can quickly get the result of encoding and decoding.)
