Patent ID: 7826341

Claim:
A device for pseudo-noise signaling for decoding a data packet, comprising: a transceiver for receiving and transmitting at least one data packet comprising a first signal symbol, a second signal symbol, and data; communication logic operable to allow communication according to a wireless protocol; stealth signal logic operable to modulate a programmable stealth signal onto a quadrature branch of a first signal symbol such that a plurality of quadrature components of the programmable stealth signal is not detectable to a legacy device, stealth signal logic also operable to detect and interpret a stealth signal; a quasi-noise detector coupled to the communication logic, the quasi-noise detector compares sub-carrier noise component values of a received wireless signal with predetermined quasi-noise component values and asserts a signal when the noise component values of the received wireless signal correspond with the predetermined quasi-noise component values indicating that the received data packet also has the stealth signal; and a physical medium dependent sub-layer for comparing a plurality of quadrature components of the received data packet with a plurality of predetermined complex components and changing a mode of operation to decode the remainder of the data packet, if the quadrature components of the received data packet match the predetermined quadrature components, wherein the remainder of the data packet is decoded using a plurality of transmission parameters provided by the second signal symbol.
