Improved iterative detection and achieved throughputs of OFDM systems under imperfect channel estimation
Abstract--Assuming imperfect channel estimation, we propose an improved detector for orthogonal frequency-division multiplexing (OFDM) systems over a frequency-selective fading cha...

Fading observation alignment via feedback
Abstract— In some remote sensing applications, the functional relationship between the source being observed and the sensor readings may not be known. Because of communication co...

Performance Analysis of Free-Space Optical Systems in Gamma-Gamma Fading
— Atmospheric turbulence induced fading is one of the main impairments affecting free–space optics (FSO). In recent years, Gamma–Gamma fading has become the dominant fading m...

A Stochastic Model for Non-Stationary Outdoor K-Factor Variation
— A dense urban cellular environment contains many different locations where a line-of-sight or specular signal component from the base station is present. The small scale fading...
