Abstract
Continuous wave (CW) radio frequency interference (RFI) can happen in various radio frequency (RF) operating systems such as satellite and terrestrial communication systems. The efficient excision of such an RFI requires a proper detector. Accordingly, this paper investigates a computationally simple modified power detector (PD) for the detection of a CW RFI. Exact closed-form expressions are derived for the exhibited probabilities of RFI detection and of false alarm. Simulations validate the derived closed-form expressions and corroborate that the investigated modified PD performs as good as a kurtosis detector for medium to large average interference-to-noise ratio regimes though KD is more computationally complex.
