On Cluster-Based Channel Identification
Peicheng Wang, W. Ser · Procedia Engineering · 2012
In recent years, there has been an increasing interest in applying cluster analysis to channel identification and signal detection. The basic principle underlying this kind of approach is that the cluster information is directly related to the channel impulse response, and therefore it is possible to learn the channel impulse response through cluster analysis. However, a problem that has been long neglected is whether or not the cluster information is sufficient for uniquely identifying the channel. This paper aims to provide an answer to this question.
