The performance of free-space optical (FSO) communication systems based on avalanche photodiodes (APDs) is investigated over the aggregated double generalized gamma (double GG) fading channels. The approximate average bit error rate (ABER) expression is theoretically derived in terms of the double GG distributions under moderate and strong turbulent ...

This paper presents a closed form expression of an exact average bit error rate (BER) for a time-division duplex (TDD) transmit diversity scheme employing maximal ratio combining (MRC) over time selective flat Rayleigh fading channels. In the proposed analysis, the feed back delay which degrades the BER performance is taken into account.

This paper investigates the average bit error rate performance for cooperative wireless communication schemes over independent nonidentical Nakagami-m fading channels with arbitrary fading parameters. The network consists of multiple dual-hop nonregenerative relays in addition to a direct path to achieve the cooperative diversity with maximal ratio ...

The average bit error rate (BER) performance of direct single-input multiple-output (SIMO) free-space optical link over correlated non-Kolmogorov turbulence fading channels is studied. In particular, the new closed-form expressions of BER performance of maximal ratio combining (MRC) and equal gain combining (EGC) receive-diversity systems are derived ...

Optics Letters, 2013
In this Letter we propose a closed-form expression for the average bit error rate of intensity modulation/direct detection free-space optical systems employing dual-branch equal-gain combining and operating over turbulence channels. To offer a realistic error performance of the considered system we assume that both branches undergo independent but not ...

Based on the space diversity reception, the binary phase-shift keying (BPSK) modulated free space optical (FSO) system over Malaga (M) fading channels is investigated in detail. Under independently and identically distributed and independently and non-identically distributed dual branches, the analytical average bit error rate (ABER) expressions in ...

Abstract : We develop two new models for gated, pulsed radio frequency interference (RFI), one for cycle slip performance, and one for bit error performance. We compare the results of these two models to an existing, approximate model that is currently present in ITU-R Report M.2220, herein referred to as the dynamic duty cycle factor (DDCF) model ...
