| description | With the advantages of low complexity and easy implementation，convolution code is widely used in practical communication systems. However，the requirement of higher transmission power in tactical environment of long distance transmission and higher quality of communication，results in additional energy loss，limited transmission range and relatively high bit error rate in receiver. High quality channel coding can achieve the same communication quality with lower power consumption，improving the performance of the whole system. So the basic principles of Turbo code and LDPC code were studied. The results of simulation combined with the characteristics of actual communication system，show that Turbo code and LDPC code have better performances than convolution code under the same conditions and could be used to improve the channel coding efficiency in tactical communication system. |
