用于多媒体广播的正交频分复用模块集成系统

An Integration System of Orthogonal Frequency Division Multiplexing Module for Multimedia Broadcasting

在 0 .1 8μm工艺或更小的线宽下 ,可把各单个子系统有效地集成在同一块芯片上。通过讨论新工艺条件下具有语音视频图像处理功能的高速编码正交频分复用调制 (OFDM)集成系统设计的可能方案 ,并剖析实例 ,对其离散余弦变换、快速傅里叶变换及前向纠错编码进行了分析。

Possible schemes for integration of orthogonal frequency division multiplexing (OFDM) with speech and video image processing functions are discus sed for new process conditions The discrete cosine transform, Fast Fourier Tr ansform (FFT) and forward error correction encoding of the OFDM are analyzed b ased on the computation of an actual OFDM module
