On the Estimation of Synchronous Scramblers in Direct Sequence Spread Spectrum Systems
IEEE Access, 2020 In a non-cooperative context, the receiver has no information about communication parameters; therefore, it must perform communication forensics, which is the process of identifying what information it can from the collected data.

On Effectiveness of Hopping-Based Spread Spectrum Techniques for Network Forensic Traceback [PDF]
International Journal of Networked and Distributed Computing (IJNDC), 2013 Network-based crime has been increasing in both extent and severity and network-based forensics encapsulates an essential part of legal surveillance. A key network forensics tool is traceback that can be used to identify true sources of suspects.

On cracking direct‐sequence spread‐spectrum systems [PDF]
Wireless Communications and Mobile Computing, 2009 AbstractSecure transmission of information over hostile wireless environments is desired by both military and civilian parties. Direct‐sequence spread‐spectrum (DS‐SS) is such a covert technique resistant to interference, interception, and multipath fading.
