The Role of Pitch Filter in Pulse-by-Pulse Reoptimization of the LP Synthesis Filter
نویسنده
چکیده
Two iterative analysis algorithms were developed for the reoptimization of the LP synthesis filter based on a pulse-by-pulse reoptimization manner. In this study, the use of the pitch filter in the analysis algorithms is introduced. Similar to the no pitch case, improvement in the gain is achieved. On the other hand, this gain has dropped compared to the no pitch case. Moreover, the number of pulses needed to reoptimize the LP filter found to be much less than that, in the no pitch case. صخلم كلذو ةيعيمجتلا ةعقوتملا ةيطخلا تاحشرملا ءادأ نيسحت لجا نم نيتيليلحت نيتقيرط ريوطت مت دقل ةيعيمجتلا ةيلمعلا يف ةمدختسملا تاضبنلا ددع ىلع دامتعلااب . دوجو ريثأت ةسارد تمت دقلف ثحبلا اذه يفو رملا يكولسلا طمنلا سفن هل ةيمزراوخلا كولس نأ ظحول ثيح تايمزراوخلا ءادأ ىلع ىدملا ليوط يطخلا حش ضفخنا دق بسكلا اذه رادقم نأ ريغ ماعلا بسكلا رادقم يف نسحت ققحت ظحول ذإ همدع وأ حشرملا اذه دوجوب حشرملا اذه دوجو مدع عم لاحلا هيلع وه امع . نأ ظحول دقف ىرخأ ةيحان نم و لجأ نم ةمزلالا تاضبنلا ددع حشرملا اذه بايغب ةلثمتملا ةلاحلا يف كلت نم لقأ يه تاحشرملا ءادأ نيسحت .

Extending the Radar Dynamic Range using Adaptive Pulse Compression
The matched filter in the radar receiver is only adapted to the transmitted signal version and its output will be wasted due to non-matching with the received signal from the environment. The sidelobes amplitude of the matched filter output in pulse compression radars are dependent on the transmitted coded waveforms that extended as much as the length of the code on both sides of the target loc...

متن کاملA Novel 36-pulse rectifier with low kVA rate to reduce harmonic input current distortion
The increase in the number of pulses in multipulse rectifiers leads to a reduction in harmonic current distortion. But this increase in the number of pulses leads to an increase in kVA, cost, and complexity of the multi-pulse rectifiers. As a result, in industrial applications, 12-pulse rectifiers are mainly used due to their lightweight, simple transformers, and low kVA rate, and low cost. The...
