Nakagami-m Fading Channels

Abstract: This paper is concerned with the analysis of exact symbol error probability (SEP) for cooperative diversity using amplify-and-forward (AF) relaying over independent and non-identical Nakagami-m fading channels. The mathematical formulations for Probability Density Function (pdf) and Moment Generating Function (MGF) of a cooperative link have been derived for calculating symbol error p...

Adaptive M-qam Modulation over Nakagami Fading Channels

We study the performance of constant-power variable-rate M-QAM schemes over Nakagami fading channels. We obtain closed-form expressions for the outage probability, spectral eeciency and average bit-error-rate (BER) assuming perfect channel estimation and negligible time delay. For a target BER of 10 ?3 , the spectral eeciency of adaptive continuous rate M-QAM comes within 5 dB of the Shannon ca...

Cooperative mobile-to-mobile communications over double Nakagami-m fading channels

Double Nakagami-m fading model can be used to provide a realistic description of the mobile-to-mobile (M2M) channel. The moment generating function (MGF)-based approach is used to derive the symbol error probability (SEP) expressions for the multiple-mobile-relay-based M2M system. Under the consideration of better performance and lower complexity, both decode-and-forward (DF) and amplify-and-fo...

Analysis of Energy Detection Over Cascaded Nakagami-m Fading Channels

In this paper, the problem of spectrum sensing using energy detection over cascaded Nakagami -m fading channels was addressed where all terminals are considered as vehicles. Closed-form expressions of detection probability were derived based on probability density function method. The validity of theoretical analyses was shown by comparing numerical results with Monte-Carlo simulations. The res...
