Quasisynchronous LoRa for LEO Nanosatellite Communications

no code implementations1 Aug 2023 Hasan Gokhan Uysal, Ferkan Yilmaz, Hakan Ali Cirpan, Oguz Kucur, Huseyin Arslan

Even by incorporating atomic clocks in LEO satellites, their inherent precision can be leveraged to enhance the overall synchronization process, perfect synchronization is infeasible due to a combination of factors such as signal propagation delay, Doppler effects, clock drift and atmospheric effects.

New Results on the Sum of Gamma Random Variates With Application to the Performance of Wireless Communication Systems over Nakagami-m Fading Channels

3 code implementations12 Feb 2012 Imran Shafique Ansari, Ferkan Yilmaz, Mohamed-Slim Alouini, Oğuz Kucur

The probability density function (PDF) and cumulative distribution function of the sum of L independent but not necessarily identically distributed Gamma variates, applicable to the output statistics of maximal ratio combining (MRC) receiver operating over Nakagami-m fading channels or in other words to the statistical analysis of the scenario where the sum of squared Nakagami-m distributions are user-of-interest, is presented in closed-form in terms of well-known Meijer's G function and easily computable Fox's H-bar function for integer valued and non-integer valued m fading parameters.
