Abstract :
This paper proposes and evaluates a reception chip-level synchronization scheme for ad-hoc enabled UTRA-TDD networks. Since ad hoc users directly communicating with each other, the conventional pilot signals from base stations are no longer available for chip-level synchronization. A new scheme of using the training sequences (midamble) in each traffic time slot with customized correlation detection window is proposed for the synchronization establishment and maintenance for any single hop direct links. Link-level simulations are performed to evaluate the performance of the scheme. The conventional method using pilot signals from base stations are tested for benchmarking. The results show that using midamble for the reception synchronization for ad-hoc enabled UTRA-TDD networks is feasible.
