  • Publication number: 20200100067
    Abstract: In an example embodiment, a device comprises one or more processors and a baseband controller. The one or more processors are configured to: determine, from a payload of at least one received packet, a channel identification (ID) of a notice window in a sequence of transmission windows; transmit, in the notice window, a notice packet that identifies a target window, the target window being later in the sequence of transmission windows than the notice window; generate a target packet that includes inverse whitened data; and transmit the target packet in the target window. The baseband controller is configured to execute signal whitening on the target packet, where the signal whitening of the inverse whitened data in the target packet results in a substantially sinusoidal signal when the target packet is transmitted by the device.
