Description: 信道编码的实质是在信息码中增加一定数量的多余码元(称为监督码元),使它们满足一定的约束关系,这样,由信息码元和监督码元共同组成一个由信道传输的码字。一旦传输过程中发生错误,则信息码元和监督码元间的约束关系被破坏。在接收端按照既定的规则校验这种约束关系,从而达到发现和纠正错误的目的。它在数字通信方面得到了广泛的应用。本文将简要介绍信道编码原理及其应用,并详细介绍本次设计所用到的(7,4)汉明码的编码译码原理、DPSK调制解调的原理并在MAXPLUS II上用VHDL语言实现。

Description: vhdl,Digital phase modulation is also known as phase shift keying, 2DPSK is binary differential phase shift keying, is a kind of digital phase modulation. Digital phase modulation using carrier phase change to transmit digital signal, usually can be divided into it absolute phase shift ( BPSK ) and the relative phase shift ( DPSK ). Relative phase shift is the use of digital information and the adjacent symbols to determine relative carrier phase difference carrier phase. This paper mainly introduces the 2DPSK modulation and demodulation process and the use of phase selection method to achieve the process. And the principle of the key analysis, including modulation and demodulation principle, as well as in the modulation and the demodulation process utilizing principle to achieve absolute code and relative code generation.-Digital phase modulation is also known as phase shift keying, 2DPSK is binary differential phase shift keying, is a kind of digital phase modulation.
