This paper describes study results regarding a feature detection scheme using a Cyclic Prefix (CP) that is appended to an OFDM signal. The detection scheme is especially important when used as a sensing technology in advanced systems such as Device-to-Device communication. Herein, several performance characteristics of the signal processing involved in the feature detection are described with an analytical expression and examined with software simulation. Then, supposing that two OFDM systems using different CP lengths are operated in the same frequency band, some applications are addressed such as an estimation method for the Input C/N (Carrier-to-Noise power ratio), a system discrimination scheme and a timing offset detection method.
