Wireless network discovery and synchronization using spatial processing
The patent US12040921B1 outlines a method and system for detecting synchronization signals in a communication system using advanced signal processing techniques. The method involves searching for a synchronization signal by applying a spatial matched filter, which incorporates a spatial whitener, to signals received by multiple antennas. This process is complemented by the use of multiple adaptive beamformers that detect various signal parameters, including carrier frequency and timing offsets, from the synchronization signal. The method can be executed at a remote node within the communication system, with synchronization signals being transmitted from a base station.
The system described in the patent consists of a plurality of antennas connected to a spatial matched filter and multiple adaptive beamformers. The spatial matched filter is designed to identify synchronization signals from incoming signals, while the adaptive beamformers are tasked with detecting specific parameters within those signals. Each beamformer utilizes cross-correlation vectors and inverse spatial covariance matrices to optimize detection. Additionally, the system can generate training sequences to enhance the accuracy of parameter detection, further improving the reliability of synchronization in communication networks.
