In Drosophila melanogaster the syndrome of germline abnormalities generated in the P-M system is caused by transposable elements known as the P element family. The frequency of gonadal dysgenesis, GD sterility characteristic of the P-M system, was estimated in 120 populations, collected in 1980-1983 from arround the world, in order to determine the present(More)
In this paper, second order statistics such as, Autocorrelation (ACF), Level crossing rate (LCR) and average fade duration (AFD) of an improved deterministic model is analyzed. Simulation results are presented by using different methods for the design of the parameters of the deterministic simulation model. Compared to the generalized method of exact(More)
In this paper, an improved parameter computation method is proposed for generation of multiple uncorrelated Rayleigh fading waveforms. The improved method employs random Doppler frequency wobble for all individual sinusoids based on the original Exact Doppler Spread Method (MEDS), and when the random wobble amplitude is set to be an infinitesimal real(More)
The generation of multiple uncorrelated mobile-to-mobile Rayleigh fading waveforms is essential for simulating frequency selective mobile-to-mobile channels, multiple-input multiple-output (MIMO) mobile-to-mobile channels, and diversity-combined mobile-to-mobile channels. In this paper, a new deterministic model based on Rice's sum of sinusoids (SOS) and(More)
In this paper, a new technique which employs random wobble on the method of exact Doppler spread (MEDS) for the design of high performance Rayleigh fading channel simulators was proposed. The new method could be used on any deterministic parameter computation method in theory, such as the method of equal areas (MEA), the method of equal distance (MED) and(More)
