摘要： Methods and systems for estimating an angle of arrival are provided. In an embodiment, a system for estimating angle of arrival includes a snapshot determining module configured to receive a signal from each antenna of an antenna array and to generate a snapshot vector including values based on the signals and an angle of arrival processing module configured to estimate an angle of arrival for the electromagnetic signal relative to the antenna array based on the snapshot vector. Each signal is representative of an electromagnetic signal incident on a respective antenna of the antenna array and each value is representative of a phase of a respective signal.

摘要： A signal acquisition system efficiently acquires a transmitted signal even at very low power. The system may synchronize to a preamble structure in the transmitted signal and, for example, determine timing parameters that locate the preamble with respect to system timing or other clock references. The system is particularly effective at acquiring weak power signals and is also robust against significant noise and other impairments, and therefore improves the ability of a receiving device that incorporates the signal acquisition system to acquire the signal and establish communication with other devices.
