A Companding Technique to Reduce Peak-to-Average Ratio in Discrete Multitone Wireline Receivers
IEEE Open Journal of Circuits and SystemsMulticarrier modulation, while providing a theoretical pathway to data rates approaching the Shannon limit and being extensively utilized in wireless communication, has encountered limited application in high-speed wireline communication. This limitation is primarily due to substantial large amplitude peaks, which necessitates a reduction in the signal&

Companding techniques for PAPR reduction of OFDM systems / Chung-Ping Liaw.
, 2011 [[abstract]]在無線通訊系統中，隨著時代科技的進步，系統的傳送速率被要求愈來愈快。而正交分頻多工技術是一種多重載波調變系統，有很好的無線傳輸高資料率使用在正交頻率通道，而且可有效地抑制ISI導致多重路徑衰減在無線通道上。 但是正交分頻多工技術有一個重大缺點，就是傳送信號有很高的均峰值(PAPR)，使得系統放大器需要較大的線性區域範圍，避免產生非線性失真，導致位元錯誤率增加以及頻譜外散的現象。不過，操作線性區域變大，卻也浪費了放大器的使用效率。 因此，在本文中 ...
