本文介绍了一种在FPGA中实现的增强型正交频分复用调制器设计，它使用了逆FFT模式的莱迪思快速傅立叶变换（FFT）Compiler IP核和莱迪思有限脉冲响应（FIR）滤波器IP核。该设计解决了在没有主控制器的情况下生成复杂测试模式的常见难题，大大提高了无线链路 ...

OFDM是一种现代宽带无线通信系统应用的技术。OFDM调制中最关键的运算就是IFFT，相类似，OFDM解调的核心为FFT。宽带系统中的高FFT吞吐率是至关重要的，尤其是在FFT被多路数据通道共享时。本文提供了一个可重配置无线系统中的OFDM调制解调的实现实例，实例的 ...

Over the past year I’ve been writing about potential transmission standards for a nextgeneration broadcast platform (NGBP). The most promising standards are all based on orthogonal frequency division ...

This series is excerpted from “Mobile Broadband Multimedia Networks: Techniques, Models and Tools for 4G.” Part two shows how to enhance OFDM with MIMO and other techniques. The many papers noted in ...
