Abstract

In this paper a technique is described that permits increased receiver tolerance to uncoordinated CCI in a wireless LAN environment. The technique uses supervised clustering to determine the signal states due to ISI and a form of unsupervised fuzzy clustering for finding the signal states due to CCI. Using a decision feedback approach, it is shown that the receiver is capable of operating in high levels of CCI, providing usable error rates
