This paper analyzes the performance of an energy detector over wireless channels with composite multipath fading and shadowing effects. These effects are modeled by using the K and K_G channel models. Closed-form average detection probabilities are derived for both K and K_G channel models for the no-diversity reception case. A simple approximation is also derived for large values of energy threshold...
M-FSK modulation classification and identification of the modulation order are studied for both flat and frequency selective fading channels. In the modulation classification, M-FSK modulated signals are identified from M-PSK and M-QAM signals using amplitude and spectral features of the received signal. Once the M-FSK signal is identified, then the order of the signal is detected blindly. Various...
The problem of optimal (fixed) wireless sensor network (WSN) design for distributed detection of a randomly-located target is addressed. This is an extension of the previous work reported in [1] where the problem was addressed for a one-dimensional (1D) network assuming wireless channels between sensors and the fusion center undergo only the path-loss attenuation. In this paper we consider both one...
