08 - OFDM: Water Filling Algorithm

In this video, the sum rate of ODFM is defined. Then, an optimization problem is formulated to determine the optimum power allocation, for the different multi carriers, that maximizes that sum rate.
Afterwards, the water-filling algorithm is explained, and is used to solve for the optimum power allocations as an alternative to solving a system of equations.

الله يكرمك يارب شرح رائع وواضح ومتكامل, دكتور سامي لوسمحت فضلا منك لو تشرح لنا Estimation, equalization, synchronization that used at the receiver after wireless multipath wireless transmission (OFDM signals) بشيء من التفاصيل في مايخص الغايه منها ولماذا تستخدم وكذلك المعادلات والنموذجي الرياضي الذي يشرح مبدأ عملها اكون شاكر بجد لحضرتك الله ينور عليك دنيا واخره
