Abstract

This letter introduces a novel passive beamformer which uses Bridge function sequence as spreading sequence weights for every antenna element. The set of Bridge function sequences have zero correlation zones (ZCZs) in their cross-correlation functions (CCFs). Due to the ZCZ properties of Bridge function sequences, the introduced passive beamformer features a much better performance on avoiding synchronization errors than the passive beamformers utilizing other spreading sequences without ZCZ.The theoretical justification of the proposed approach is presented in detail and the achievable performance is verified through computer simulations.
