Abstract
Abstract Various exemplary embodiments relate to a device for performing a method of communication transmission. The device may include a memory; a processor configured to: determine a spreading code with low sidelobe levels in its autocorrelation sequence to be used; create a Start of Frame Delimiter (SOFD) for a packet including the spreading code and a cyclic prefix, wherein the cyclic prefix is a portion of the spreading code; and transmit the packet with the SOFD.
