The performance of energy detection (ED) for independent and identically distribution (i.i.d.) signal models is analyzed over generalized composite non-linear line-of-sight (LOS) and non-line-ofsight (NLOS) shadowed fading scenarios. The novel expressions for ακ-μ/Gamma and α-η-μ/Gamma fading channels have been derived to approximate by using the mixture gamma (MG) distribution under low instan...

This study compared conventional static fading, where the problem solving responsibility of the learner increases at a fixed sequence, with a novel adaptive fading design in which the learner assumes more problem solving responsibility only if her or his previous solution attempt is successful. This study was conducted in the engineering knowledge domain of introductory electrical circuit analy...

Absrract---Modulated backscatter is a RF transmission technique useful for short-range, low-data-rate applications constrained to have extremely low power requirements, such as electronic shelf tags, RF tags, and some sensor applications. The small-scale fading observed on the backscattered signal has deeper fades than a signal from a traditional one-way link of the same range in the same envir...

In this paper, we analyze the Bit Error Rate (BER) performance of Golden coded Multiple-Input Multiple-Output Orthogonal Frequency Division Multiplexing (MIMO-OFDM) system over Rician multipath fading channel. We also compare the performance of the MIMO-OFDM system using Golden code in Rayleigh and Rician multipath fading channels. We discuss the effects of the presence of line-of-sight (LoS) c...

Abstract— In this work, the performance of turbo codes over the Rice multiplicative fading channel is evaluated through analysis and simulation. The analysis is conducted through improved upper bounds on bit error probabilities in conjunction with both the fully interleaved channel and the correlated Rice slow fading channel. The analytical expression of the improved bound is obtained by extend...

Little is known about the characteristics of meals that serve as motivating operations (MOs) for escape behavior. In the current investigation, we showed that the distance at which a therapist held a spoon from a child's lips served as an MO for escape behavior. Based on these results, we implemented spoon distance fading, compared fading with and without escape extinction (EE), and compared fa...

The coherent reception of Direct Sequence Code Division Multiple Access(DSCDMA) signals in a multipath fading channel is considered. The channel model assumes independent paths with Nakagami fading statistics. This model includes the Rayleigh channel as a special case and a reasonable model for a frequency selective fading channel. The bit error rate(BER) performance of a RAKE receiver under va...

In this paper we review the most peculiar and interesting information-theoretic and communications features of fading channels. We first describe the statistical models of fading channels which are frequently used in the analysis and design of communication systems. Next, we focus on the information theory of fading channels, by emphasizing capacity as the most important performance measure. Bo...

The paper presents a technique to transmit 16QAM signals in mobile radio environments. The conventional method for compensating the multipath fading e ect using pilot symbol assisted modulation (PSAM) is extended, employing not only the pilot symbols but also the previously estimated fading values for evaluating the fading in the current frame. The main results of this paper are the symbol erro...
