In recent years, optical orthogonal frequency division multiplexing (OOFDM) has emerged as a dominant research and development area in the field of high-speed optical communications. OFDM is a potential candidate as the most promising next-generation optical networks such as passive optical networks and optical transport networks, due to their simple configuration based on low cost, high speed data rates, high spectral efficiency, high quality of service and robustness against narrow band interference, frequency selective fading, and chromatic dispersion.

Dams and particle separation is important in the process of harvesting rice (rice; wheat) and energy intensive. There have been many studies on various parts of the dam to improve your drum beats combine harvesters were introduced in recent years. Research division beating drums beating two types of tangential to the direction tangential feed was made in 2007 with the aim of: increasing particle separation distribution of the dam, the dam reduced energy costs, reduce the impact split ...
