In this paper, we derive bit error performance bounds for turbo codes on Nakagami fading channels with diversity combining. We first derive the average pairwise error probability expressions for turbo codes with maximal ratio combining (MRC), equal gain combining (EGC), and selection combining (SC) on Nakagami fading channels. Using the pairwise error probability expressions and the union bound...

By realizing the concept of implementation of the radio propagation channels on simulators is the eminent intention of this work. Even though prototyping software simulators are effortless to design we prefer hardware simulators as they endeavors distinguishable quickness, compared to earlier. Prior to this work fading channels like Gaussian, Rayleigh and Rician fading channel simulators were e...

In this paper, we propose an online SNR estimation scheme for Nakagami-m fading channels with equal gain diversity combining. We derive the SNR estimates based on the statistical ratio of certain observables over a block of received data. An online SNR estimator for an AWGN channel has been derived by Summers and Wilson. Recently, we derived an SNR estimation scheme for Nakagami-m fading channe...

Wind energy is among the renewables that have grown fastest in recent times. Since it can be considered as a notably clean and sustainable alternative, this trend likely to continue years come. In particular, offshore wind has received an increasing amount of attention for two main reasons: i) its high potential ii) difficulty certain countries experience finding suitable terrain new onshore fa...

Cooperative diversity uses relays which assist source destination transmissions to reduce link outage rates in multipath fading environments. In this paper, an Amplify-and-Forward (AAF) cooperative communication system over Nakagami-m fading channel is considered where a source node communicates with a destination node directly and indirectly (through multiple relays). Nakagami-m fading channel...

In this paper we present the performance of two uplink/downlink DS-CDMA receivers in a Nakagami wideband channel. Two detection methods were considered; namely, coherent and differential detection RAKE receivers based on maximal ratio combining technique. We consider a new physical interpretation of the Nakagami channel and the instantaneous power of the multiple access interferers. In comparis...

It has been well known that the suitable criteria for Space time trellis codes (STTC) designed over slow Nakagami fading channel for product of rank and number of receiver antennas ) are maximization of minimum rank and maximize the minimum product of nonzero eigenvalues for rank and determinant criteria. But for large product i.e. for ), the design of codes with minimum error probability and m...

Spectrum sensing is the key component of cognitive radio technology. Spectrum sensing is a tough task because of shadowing, fading, and time-varying nature of wireless channels. However, detection is compromised when a user experiences shadowing or fading effects. In such cases, user cannot distinguish between an unused band and a deep fade. Thus, cooperative spectrum sensing is proposed to opt...

In this study, the authors investigate the error rate performance of amplify-and-forward relaying over N∗Nakagami fading channels. This is a recently introduced channel model that involves the product of N Nakagami-m-distributed random variables. Employing the moment generating function approach, the authors derive symbol error rate expressions for a single-relay system under instantaneous powe...
