摘      要：Random access is a well-known multiple access method for uncoordinated communication *** work mainly focuses on optimizing iterative access protocols,assuming that packets are corrupted once they are collided,or that feedback is available and can be *** practice,a packet may still be able to be recovered successfully even when collided with other *** design and performance analysis under such a situation,particularly when the details of collision are taken into consideration,are less *** this paper,we provide a framework for analytically evaluating the actual detection performance in a random temporal multiple access system where nodes can only *** expressions are provided for collision probability and signal to interference and noise ratio(SINR)when different numbers of packets are *** then discuss and compare two receiver options for the AP,and provide detailed receiver design for the premium *** particular,we propose a synchronization scheme which can largely reduce the preamble *** also demonstrate that system performance could be a convex function of preamble length both analytically and via simulation,as well as the forward error correction(FEC)coding rate.
