考虑是否通过反馈来增加离散时间高斯信道的容量的问题。众所周知，白高斯信道在平均功率约束下的容量不会因反馈而改变。给出了通过反馈增加带分块白噪声的非白高斯信道容量的必要条件。 >
The problem of whether the capacity of a discrete-time Gaussian channel is increased by feedback or not is considered. It is well known that the capacity of a white Gaussian channel under an average power constraint is not changed by feedback. The necessary condition under which the capacity of a nonwhite Gaussian channel with blockwise white noise is increased by feedback is given. >
