Watermarks for wireless communications |
摘要 |
In a communication system comprising a plurality of transmit/receive units (TRUs), a method for embedding a watermark into data includes modifying a carrier signal containing data to embed watermark information. The modified carrier signal is transmitted. A receiver receives the modified carrier signal and extracts the watermark information from the modified carrier signal.
