摘要

本文研究了turbo编码在频谱高效频分复用(SEFDM)系统中的设计和应用，该系统故意违反正交性以提高频谱效率(SE)。该工作详细介绍了一个带有软解码器的新提出的系统结构，并研究了该系统在不同信道条件和不同压缩因子值(即频谱效率)下的行为。此外，将采用turbo编码和解码的SEFDM系统的性能与使用卷积编码和带有干扰抵消(IC)的接收端turbo均衡的SEFDM系统进行了比较。

Comparison of turbo decoder and turbo equalizer for spectrally efficient FDM system

This paper investigates the design and application of turbo coding in spectrally efficient frequency division multiplexing (SEFDM) systems, where orthogonality is intentionally violated to increase spectral efficiency (SE). The work details a newly proposed system structure with a soft decoder and investigates the behavior of such system under different channel conditions and different values of compression factors (i.e. spectral efficiencies). Furthermore, the performance of SEFDM with turbo coding and decoding is contrasted with that of reported SEFDM systems using convolutional coding and receiver turbo equalization with interference cancellation (IC).
