Abstract
An apparatus, a method and a computer program for determining a bearing. The apparatus may comprise: a first transformer configured to transform a first signal formed from a set of multiple orthogonal subcarriers and received via a first path, from a time domain to a frequency domain and produce for each of a plurality of the multiple orthogonal subcarriers a respective first coefficient; a second transformer configured to transform a second signal formed from the set of multiple orthogonal subcarriers and received via a second path, different from the first path, from a time domain to a frequency domain and produce for each of a plurality of the multiple orthogonal subcarriers a respective second coefficient; and processing circuitry configured to process the plurality of first coefficients and the plurality of second coefficients to determine a bearing for the apparatus.
