An Adaptive Symbol Timing Synchronization Method for Multi-Mode & Multi-Service Software Radio Communications Systems

摘要

A symbol timing synchronization method is proposed for the realization of a multi-mode and multi-service software radio receiver. The method enables an accurate search for the optimum symbol timing without any redundant hardware such as sampling rate conversion devices, when the system clock in non-integer times for the target systems' symbol rates. Accord- ingly, a multimode and multi-service receiver can set an arbitrary system clock for the target systems' symbol rates, and the number of A/D converters can be reduced to the minimum.
