The proposed synchronizer can be utilized as matlab reference for comparing matlab programming performance of different suboptimal frame synchronizers. We also modify matlab programming proposed frame synchronizer to reduce matlab programming implementation complexity and propose matlab near ML synchronizer for time varying fading channels. A constant envelope OFDM scheme with phase modulator PM CE OFDM for 6PolSK QPSK modulation was tested. Performance under large fiber launch power is measured to envision its merits in counteracting fiber nonlinear impairments. In our simulation, PM CE OFDM, RF assisted consistent envelope OFDM RF CE OFDM and traditional OFDM Con OFDM are transmitted via 80 km normal single mode fiber SSMF single channel and WDM system. Simulation results verify that PM CE OFDM has best functionality in resisting fiber nonlinearity. The turbulence is simulated by k based shear stress shipping SST turbulence model along with computerized near wall treatments. Four types of simulations were performed for matlab programming runner geometry with out hub clearance, with only matlab programming hub front clearance, with only matlab programming rear hub clearance, and with both front and rear clearance. The research of matlab programming obtained results is targeting matlab programming flow structure of matlab programming hub clearance flow, matlab programming effect on matlab programming turbine functionality adding hydraulic efficiency and cavitation performance, that could improve matlab programming information on matlab programming flow field in matlab Kaplan turbine. The rotor hub system is by far matlab programming biggest contributor to helicopter parasite drag and matlab barrier to expanding helicopter forward flight speed and range. Additionally, matlab programming hub sheds undesirable vibration and instability inducing unsteady flow over matlab programming empennage. The challenges associated with rotor hub flows are mentioned, adding bluff body drag, interactional aerodynamics, and matlab programming effect of matlab programming turbulent hub wake on matlab programming helicopter empennage.
