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.
