维特比

• The columns and rows are constrained by each other . the simulations over binary symmetric channe ( lbsc ) and gilbert - elliott channel ( gec ) shows the performance is great improved , especially over burst error channel peak signal to noise ratio ( psnr ) is improved more . it is tried to be used in wireless communication system
  仿真结果表明,采用行列交替约束的约束维特比译码以后,性能得到较大的提升,尤其在突发错误信道中,传输的图像经乘积编码进行信道编码与译码后峰值信噪比有明显的提高。
