衛星通信へのOFDMの適用(衛星通信技術及び一般(JC-SAT2007)) OFDM for satellite communications(Modem Technology)

Abstract

マルチキャリヤ伝送方式あるいはOFDM方式は地上系無線通信システムでのキーテクノロジーとしての重要性が増している.これは,単にシングルキャリヤ伝送方式に対する利点だけで無く既存の多くのアプリケーションによるところも大きい.しかしながら,衛星通信においては,非線形増幅器の影響が大きく,まだOFDMを適用した例は無い.本項では,OFDMの非線形増幅の影響を緩和する方式を述べていき,衛星通信へのOFDMの適用について述べていく.

OFDM or multicarrier systems have emerged as a key technology for current existing terrestrial wireless systems. Because of their advantages over a single carrier system, OFDM is undergoing rapid progress and inspiring numerous applications. However, many technical issues still exist for adopting OFDM to satellite communications, i.e., non-linear amplifier compensation. In this article, we present a detailed investigation of various non-linear compensation techniques and provide a better understanding of the research challenges.
