Abstract

Efficient timing synchronization in an IDMA system must be obtained before signal detection and decoding. However, the research on timing synchronization in IDMA system has not been studied widely. In this paper a new timing acquisition scheme for asynchronous IDMA uplink based on sliding correlation is proposed and its performance in terms of the probability density function is developed. The simulation results show that the proposed scheme is effective even under high MAI conditions.
