Performance simulation of the proposed estimator including mean squares error ( mse ) of channel and uncoded bit error rate ( ber ) have been taken , and the results show the estimator is efficient and very flexible
对信道盲估计的均方误差( mse )和由此算法获得的信道的状态信息，对无编码的ofdm系统进行解一调的误比特率进行了仿真。
The paper discusses the part of asic design of tcm ( trellis coded modulation ) in hdtv 8vsb terrestrial channel broadcasting receiver chip . in testing , the tcm can improve the signal - to - noise by 3 . 3db compared with uncoded 4 - vsb modulation , and with the 12 path intrasegment interleaving in tcm coding and viterbi decoding , system can control short burst noise error efficiently
在高清晰度电视信道接收芯片中内码是8 ? vsb的格状编码，在系统性能上使用tcm编码要比未编码有3 . 3db的编码增益，另外在格状编码中加入了12路的内交织，可有效的抑制短的突发噪声对接收端viterbi解码性能的影响。
