One of the most challenging topics for next - generation wireless networks is the process of discrimination among signals, since many of wireless technologies overlap each other and build a heterogeneous topology. The conventional signal's detection methods like Matched Filter detector, Energy Detector and Feature Detector cannot give us an indication about the type of signals. Also suffer from many drawbacks like complexity in design, determining the value of threshold level and increasing probability of false alarm (Pf) in high noise level etc. This work considered the differentiation and discrimination between GSM and WiMAX signals in noisy environment. Our discriminator (Bouncy Detector (BD)) is an extension for Hop Rate Detector's (HRD). It was basically designed to detect and estimate the hop rate of frequency hopping signals only. The simulation results show that BD can work properly and accurately without confusion between the signals even in highly noise environment.
