Radar signal detector for wireless local area network system, has signal determining block detecting incoming signal nature upon comparing merit index with one threshold value and estimating angular frequency relative to another value

摘要

The detector has a digital computer (3) calculates an actual phase of a signal. A block (6) determines a difference between initial and actual phases. A signal generating block (8) generates a complex exponential signal. A signal determining block (11) detects nature of an incoming signal upon comparing a merit index with a preset threshold value and estimating an angular frequency relative to another threshold value. An independent claim is also included for a process for detecting a signal in a wireless local area network system.
