Apparatus comprises a memory configured to store a matrix of transmit data; a multi-element antenna; and a transmitter configured to transmit a signal from a multi-element antenna as part of a packet within a transmit period in a switching interval by: switching between different elements of the multi-element antenna in a sequence of transmit intervals within the transmit period; and deriving the signal for transmission in different transmit intervals from different ones of the transmit data in the matrix. Also, apparatus comprises a receiver configured to receive plural packets; and an accumulator configured, for each packet, to accumulate signals received in a switching interval of the packet. The apparatus is configured to: derive a correlation metric for each of the packets from the accumulated signals for the packets; identify a packet with the best correlation metric; identify a direction associated with the packet identified as having the best correlation metric; and provide the direction as an output.

One of the embodiments of the present invention relates to a method for modulation. The method comprises: providing a first bit sequence of continuous bits “1” or continuous bits “0” generating a second bit sequence by replacing, in each of a plurality of modulation intervals with a predetermined bit number, at least one bit of the first bit sequence at at least one fixed position of the respective modulation interval with one information bit from an information bit sequence; and modulating the second bit sequence so as to generate a positioning packet with a modulated continuous wave signal for transmission. The embodiments further relate to a method for demodulation. Embodiments of the present invention also provide corresponding apparatuses and computer program products.
