商品描述

Orthogonal Frequency Division Multiplexing (OFDM) systems are widely used in the standards for digital audio/video broadcasting, WiFi and WiMax. Being a frequency-domain approach to communications, OFDM has important advantages in dealing with the frequency-selective nature of high data rate wireless communication channels. As the needs for operating with higher data rates become more pressing, OFDM systems have emerged as an effective physical-layer solution. This short monograph is intended as a tutorial which highlights the deleterious aspects of the wireless channel and presents why OFDM is a good choice as a modulation that can transmit at high data rates. The system-level approach we shall pursue will also point out the disadvantages of OFDM systems especially in the context of peak to average ratio, and carrier frequency synchronization. Finally, simulation of OFDM systems will be given due prominence. Simple MATLAB programs are provided for bit error rate simulation using a discrete-time OFDM representation. Software is also provided to simulate the effects of inter-block-interference, inter-carrier-interference and signal clipping on the error rate performance. Different components of the OFDM system are described, and detailed implementation notes are provided for the programs. The program can be downloaded here. Table of Contents: Introduction / Modeling Wireless Channels / Baseband OFDM System / Carrier Frequency Offset / Peak to Average Power Ratio / Simulation of the Performance of OFDM Systems / Conclusions

商品描述(中文翻譯)

正交頻率分割多工(Orthogonal Frequency Division Multiplexing, OFDM)系統廣泛應用於數位音頻/視頻廣播、WiFi 和 WiMax 的標準中。作為一種頻域通信方法,OFDM 在處理高數據速率無線通信通道的頻率選擇性特性方面具有重要優勢。隨著對更高數據速率操作需求的日益迫切,OFDM 系統已成為一種有效的物理層解決方案。

本短文獻旨在作為一個教程,強調無線通道的有害方面,並說明為何 OFDM 是一種能夠以高數據速率傳輸的良好調變選擇。我們將採取系統級的方法,指出 OFDM 系統的缺點,特別是在峰值與平均功率比(peak to average ratio)和載波頻率同步的背景下。最後,OFDM 系統的模擬將受到重視。提供了簡單的 MATLAB 程式,用於使用離散時間 OFDM 表示法進行位元錯誤率模擬。還提供了軟體以模擬區塊間干擾、載波間干擾和信號削波對錯誤率性能的影響。描述了 OFDM 系統的不同組件,並為程式提供了詳細的實現說明。該程式可以在此下載。
