Processing signals |
摘要 |
Signals are received, over a range of angles, at an input of a device. The signals include a primary signal with a principal direction of arrival and an interfering signal with a respective interfering direction of arrival at the input. Measurements are determined for the received signals over the range of angles. Each measurement relates to a particular angle and indicating the energy of the received signals which are received from the particular angle. For each angle over the range of angles, a value is removed from the measurement for that angle, the value being based on the minimum of: (i) the energy of the measurement for that angle, and (ii) the energy of a corresponding measurement for a corresponding angle mirrored around the principal direction of arrival, whereby the remaining values of the plurality of measurements are indicative of said at least one interfering direction of arrival. |

1. A method of processing signals at a device, the method comprising:
receiving signals, over a range of angles, at an input of the device, the signals including a primary signal received with a principal direction of arrival at the input and at least one interfering signal received with a respective at least one interfering direction of arrival at the input; determining a plurality of measurements for the received signals over the range of angles, each measurement relating to a particular angle and indicating the energy of the received signals which are received from the particular angle; and for each angle over the range of angles, removing from the measurement for that angle a value based on the minimum of: (i) the measurement for that angle, and (ii) a corresponding measurement for a corresponding angle mirrored around the principal direction of arrival, whereby the remaining values of the plurality of measurements are indicative of said at least one interfering direction of arrival. |
