MATLAB simulation of Viterbi decoding algorithm
Abstract:     With the development of science and technology, mankind entered the era of information highly developed. In the fields of politics, military, economy, understood the importance of information, research on information theory are more and more attention. Since ancient times, the information just as matter and energy, is one of the basic resource for human survival and development. The history of human communication can be traced back to ancient times, text, beacons, flames and inn as the main means of communication, have lasted thousands of years. In a wireless communication system, in order to overcome data transmission errors, the need for error control coding. Convolution coding is a good error correction coding method. It takes full advantage of the correlation between the groups, increased supervision element of this group is not only about the information element, and a relationship with the previous several groups of digital information, which is the basic idea of the convolutional code. Since each school inspection numbers and more digital information, whether in theory or in fact have proved superior to block codes. And convolution codes corresponding Viterbi decoding algorithm is the additive white Gaussian noise (additive white gaussian noise, AWGN) channel under optimal decoding algorithm convolution codes in the data channel and satellite communications have been widely used. 源￥自%六^^维*论-文+网=www.lwfree.cn
