Joint Uniform Distribution Companding for Nonlinear Effects in OFDM Systems

, 2011
[[abstract]]正交分頻多工技術(OFDM)是一種高頻譜效率的多載波傳送技術，但OFDM傳輸技術其缺點有高的峰值對平均值之功率比值(PAPR)，因此要求系統中的功率放大器和類比數位轉換器皆要具有較大的線性動態範圍，所以會降低系統性能、增加硬體實現難度和系統成本。 降低OFDM系統PAPR的方法有很多，大體可以分為兩類：一類的方法是會產生信號失真，如截波(Clipping)、壓縮擴展(Companding)等，對系統而言複雜度較低，不需要增加系統的複雜度和時間延滯 ...
