We derive the fading number of a general (not necessarily Gaussian) single-input multiple-output (SIMO) fading channel with memory, where the transmitter and receiver—while fully cognizant of the probability law governing the fading process—have no access to the fading realization. It is demonstrated that the fading number is achieved by IID circularly-symmetric inputs of log squared-magnitude ...

_______________________________________________________________________ Signal Fading can drastically affect the performance of terrestrial communication systems. Fading caused by multipath propagation can degrade the bit-error-rate (BER) performance of a digital communication system resulting data loss or dropped calls in a cellular system. So it is essential to understand the nature of multip...

The κ-μ / inverse gamma and η-μ / inverse gamma composite fading models are presented and extensively investigated in this paper. We derive closed-form expressions for the fundamental statistics of the κ-μ / inverse gamma composite fading model, such as the probability density function (PDF), cumulative distribution function (CDF), moment generating function (MGF), higher order moments and amou...

Multiple trellb coded modulation of constant envelope frequency and phaqe modulated signal sets (MTCM/FPM) is investigated for performance on the AWGN channel and on the one-sided normal, Rayleighand Rician-fading channels. The Nakagami-m fading model is wed as an alternative to the Ricianfading model to calciilate the error probability upper bound for trellis coded schemes on the fading channe...

It is well known that some minerals give underestimated luminescence ages due to anomalous fading. The anomalous fading follows a logarithmic decay law characterized by its slope, the socalled fading rate or g-value. Using the fading rate, Huntley and Lamothe (2001) suggested some correction for the fading underestimation of young samples (<40-50 ka). For polymineral fine grains, we observe a f...

An effort has been made to illustrate the performance of the Rayleigh fading channel models by using Qual net simulator in terms of Throughput and PDR. A scenario has developed here for the Rayleigh fading channels, with various parameter. The parameters such as data rate and speed of nodes play very important role in the performance analysis and design of the mobile ad-hoc network over the mul...

In this paper fading models are considered. In particular we divide the models into three classes by separating the received signal in three scale of spatial variation such as fast fading, slow fading (shadowing) and path loss. Moreover, several models for small scale fading are considered such as Rayleigh, Ricean, Nakagami and Weibull distributions. Slow fading is also investigated as well as ...

The jointly optimum noncoherent multiuser detector for DPSK modulation in generalized diversity Rayleigh fading channels (GDRF) was presented in [1] and bounds on the error probability were obtained. In the numerical examples of [1] these bounds were seen to converge. This paper examines analytically the behavior of the bounds for high signal-to-noise ratio (SNR) scenarios. Slowly fading channe...

The performance of parallel and serial concatenated codes on frequency-nonselective fading channels is considered. The analytical average upper bounds of the code performance over the Rician channels with independent fading are derived. Furthermore, the log-likelihood ratios and extrinsic information for maximum a posteriori (MAP) probability and soft-output Viterbi algorithm (SOVA) decoding me...

A fading broadcast channel is considered where the transmitter employs two antennas and each of the two receivers employs a single receive antenna. It is demonstrated that even if the realization of the fading is precisely known to the receivers, the high signal-to-noise (SNR) throughput is greatly reduced if, rather than knowing the fading realization precisely, the trasmitter only knows the f...
