WATERMARKS/SIGNATURES FOR WIRELESS COMMUNICATIONS

摘要

At least one user data stream is layer 2/3 processed [24], physical layer processed [26] and radio frequency processed [28]. A watermark/signature is embedded [30] at least one of layer 2/3, [24] physical layer [24] or radio frequency [28], producing an embedded wireless communication. The embedded wireless communication is wirelessly transferred [36]. The embedded wireless communication is received [34] and the watermark/signature is extracted [34] from the embedded wireless communication.
