Abstract
Official abstract text for this publication.
A system for determining a distance between a receiver and a transmitter are disclosed herein. The transmitter includes a first antenna array having a first spatial orientation and is configured to transmit a signal. The receiver includes a second antenna array and an orientation sensor to determine a second spatial orientation of the second antenna array and is configured to receive the signal. A logic circuit is configured compare the first spatial orientation to the second spatial orientation to determine a relative orientation of the second antenna array; determine an angle of arrival of the signal; identify, based on the relative orientation of the second antenna array and the angle of arrival of the signal, a received signal strength compensation value; and calculate a distance between the transmitter and the receiver based on a measured received signal strength of the signal and the identified compensation value.
First claim
Opening claim text (preview).
What is claimed is: 1. A system comprising: a transmitter including a first antenna array having a first spatial orientation, the transmitter configured to transmit a signal; a receiver including a second antenna array and an orientation sensor to determine a second spatial orientation of the second antenna array, the receiver configured to receive the signal; and a logic circuit configured to: compare the first spatial orientation to the second spatial orientation to determine a relative orientation of the second antenna array; determine an angle of arrival of the signal; identify, based on the relative orientation of the second antenna array and the angle of arrival of the signal, a received signal strength compensation value; and calculate a distance between the transmitter and the receiver based on a measured received signal strength of the signal and the identified compensation value. 2. The system of claim 1 , wherein the logic circuit is external to the transmitter and the receiver. 3. The system of claim 1 , wherein the receiver includes the logic circuit. 4. The system of claim 1 , wherein the orientation sensor is three-dimensional sensor configured to determine a three-dimensional spatial orientation. 5. The system of claim 1 , wherein the orientation sensor is an accelerometer. 6. The system of claim 1 , wherein the received signal strength compensation value is stored in an orientation compensation profile comprising a plurality of orientation compensation values. 7. The system of claim 6 , wherein the orientation compensation values are orientation-specific received signal strength indicator (RSSI) correction gains.
