The Implementation of Physical Phase Offset Estimation In WCDMA Communication Test Set
Abstract:WCDMA communication test set plays an important role in the WCDMA terminal development and production process and is an important part of WCDMA industry chain. WCDMA communication test need to estimate the phase offset of the received uplink signal in physical layer. This paper presents a frame synchronization and phase offset estimation method based on pilot correlation, and it has been implemented in the WCDMA communication test set.This method realizes the frame synchronization and phase offset estimation in a concise way.With minimizing implementation complexity, the method has completed the phase offset estimation in the test set application environment. Practice shows that the implementation in this paper can meet the demand of the WCDMA communication test set.
