摘要:
A receiver is provided with a sequential decoder applicable to wide-area mobile communication. In an equalizer using transversal filters, for paths that are registered at the signal points where tap coefficients are small, that are within the restraint length, and that are old in time, the computation of likelihood values are performed by referring to the history of the preceding paths, thereby necessary computation is greatly reduced.
摘要(中):
接收机具有适用于广域移动通信的顺序解码器。 在使用横向滤波器的均衡器中,对于在抽头系数小的信号点处注册的路径,其在限制长度内并且在时间上是旧的,所以似然值的计算通过参考 前面的路径,从而大大减少了必要的计算。
