错误信 meaning in Chinese

error messages

Many of communication systems take the convolutional code and viterbi algorithm as the channel coding scheme . the viterbi algorithm decoding is a kind of maximum likelihood decoding , and its performance is good over additive white gaussian noise ( awgn ) channel , but when burst errors occur , the decoding performance may be greatly degraded
维特比译码算法是最大似然译码,在由高斯白噪声引起的随机错误的信道中有良好的性能,但当信道错误集中或为突发错误信道时,维特比译码算法则性能急剧下降。
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。
