Abstract
Systems and methods for low-power auto-correlation antenna selection for multi-antenna systems are disclosed. In particular, a computing device, such as an Internet of Things (IoT) computing device, may include a transceiver operating with multiple antennas. For example, the computing device may operate under a low-power wireless standard such as Long Range BLUETOOTH LOW ENERGY (LR BLE). In an exemplary aspect, an antenna from amongst the multiple antennas may be selected based on which antenna is receiving a best copy of a periodic signal. The periodic signal is likely indicative of a preamble pattern and, as such, may be used to activate a cross-correlation circuit for signal detection confirmation. Power consumption is reduced by delaying activation of the cross-correlation circuit until a likely signal is detected by detection of the periodic signal.
