SICTA modifications with single memory location and resistant to cancellation errors

Abstract

In this paper we consider a cross-layer MAC-PHY technique that combines the collision resolution tree algorithm (TA) with the possibility of successive interference cancellation (SIC). The overview of the previous work shows that no simple protocol has been proposed to use a single memory location for the captured signal. We, consequently, propose two such protocols that demonstrate the throughput - implementation complexity trade-off. Further, we address the system operation during which interference cancellation errors are possible. We propose the third protocol that is resistant to cancellation errors. A simple yet effective technique is applied to address the throughput performance of all three protocols to demonstrate their superiority over known conventional TA protocols. © 2008 Springer-Verlag Berlin Heidelberg.
