In this paper the receiver for demodulation of M-FSK signals in the presence of Gaussian noise, intersymbol interference and Rice fading will be considered. Probability density function (PDF) of M-ary FSK signals in the presence of noise, interference and fading will be derived. Key-words: M-ary Frequency Shift Keying, Probability Density Function, Gaussian noise, Intersymbol Interference, Rice...

The two-user Gaussian interference channel (G-IC) is revisited, with a particular focus on practically amenable discrete input signalling and treating as noise (TIN) receivers. corresponding deterministic (D-IC) first investigated coding schemes that can achieve the entire capacity region of D-IC under TIN are proposed. These then systematically translated into multi-layer superposition based p...

We study the covert communication over K-user-pair discrete memoryless interference channels (DM-ICs) with a warden. It is assumed that warden's channel output distribution induced by K “off” input symbols, which are sent when no occurs, not convex combination of those any other symbols (otherwise, square-root law does hold). derive exact capacity region and show simple point-to-point based sch...

An error probability analysis is performed for a noncoherent M-ary orthogonal frequency-shift keying (MFSK) communication system employing fast frequency-hopped (FFH) spread spectrum. The signal is assumed to be transmitted through a frequency-nonselective, slowly fading channel with partialband interference. The partial-band interference is modeled as a Gaussian process. The noise-normalized r...

in this paper a new algorithm is presented for coherent radar detection of targets, when distribution of the interference (clutter and noise) is non-gaussian. the neyman-pearson criterion is used for optimal detection and several successive received samples from a radar range cell are used for detection in the same cell. on the basis of recent empirical evidences, the interference distribution ...
