通信系统的仿真,卷积码是纠错码的一种,可以用于数字电视,手机等通信领域,本例子给出了基于matlab的程序，卷积码BPSK调制。-Simulation of communication systems, convolutional code is an error-correcting code can be used for digital television, mobile phones and other communications, the examples given based

BPSK仿真在AWGN信道下产生卷积码和非卷积码的比较，约束长度7，多项式[171,133],码率1/2，分别采用硬判决和软判决,Convolutional code and convolutional code comparison, simulation BPSK in AWGN channel constraint length 7 polynomial [171,133], code rate 1/2, respectively, using the hard-decision and

bpsk的调制与解调的过程，并采用卷积码，讨论其误码性能随着其功率、频偏、相偏而变化.-bpsk modulation and demodulation process and using convolutional codes, to discuss its error performance with its power, frequency offset, phase offset changes.

In this work, we are interested in the problem of the coding channel with impulsive noise, whose goal is to correct the errors due to the channel at the time of a numeric transmission. In particular, the convolutional turbocodes constitutes the last
