CTH15-6: Efficient ABER Analysis of Bandlimited Cooperative Communication under Time Synchronization Errors

Distributed multiple-input-multiple-output system (e.g., inter-cluster communication via cooperating nodes in a wireless network) is a topic of emerging interest. Much of previous studies assume perfect synchronization among cooperating nodes and identically distributed communication links. Such assumptions are rarely valid in practical operating scenarios. This paper develops an efficient analytical framework for computing average bit error rate of a distributed multiple-input-single- output (MISO) space-time coded system with intersymbol interference (due to imperfect location predictions and clock jitters between cooperating nodes, as well as the choice of data pulse shaping filters) over generalized fast fading channels. We show that under certain conditions distributed MISO system can outperform perfectly synchronized single-input-single-output (SISO) system.
