Blind Detection Algorithm of Frequency-hopping Signals Based on Cyclostationarity
Abstract:As one of spread spectrum communication, frequency-hopping signals has been widely used in military applications because of its strong anti-interference, anti-interception and spectrum sharing. The paper proposes a blind detection algorithm of frequency-hopping signals based on cyclostationarity about blind detection of frequency-hopping signals in communication countermeasures. The algorithm extends the asymptotically optimal chi-squared test to frequency-hopping signals detection, and proposes test statistics, thus completes frequency-hopping detection in Gaussian white noise environment. Experimental results show that compared with traditional energy detection method, it has better detection performance in Gaussian white noise environment, needs smaller computation, and is easy to implement.
