PAPR Reduction Techniques in LTE-OFDM Networks Год выпуска: 2012Автор: Neelam Dewangan and Mangal SinghИздательство: LAP Lambert Academic PublishingСтраниц: 84ISBN: 9783846533086Описание As a promising technique, OFDM has been widely used in many new and emerging broadband communication systems, such as digital audio broadcasting (DAB), high-definition television (HDTV), wireless local area network (IEEE 802.11a and HIPERLAN/2). However, as the OFDM signals are the sum of signals with random amplitude and phase, they are likely to have large PAPR that requires a linear high-power- amplifier (HPA) with an extremely high dynamic range, which is expensive and inefficient. Furthermore, any amplifier nonlinearity causes intermodulation products resulting in unwanted out-of-band power and also increases complexity of DAC-ADC convertors.This work describes some of the PAPR Reduction Techniques and comparison among them.

Александр, 06.01 С наступившими и грядущими праздниками Вас! Написанная Вами работа принята преподавателем как есть, мне даже пришлось буквально на месте ваять титульный лист. О недочётах она лишь сказала, что...они есть - и не более того. Благодаря Вам мне даже не пришлось сдавать экзамен по этому предмету. Спасибо большое!
