Design of All-digitized MQAM Modulator Based on Modern DSP Technology
Author(s): 
Pages: 41-42,46
Year: Issue:  9
Journal: Video Engineering

Keyword:  FPGASystem Generator;
Abstract: 利用MQAM调制的基本原理,采用基于ISE DS的System Generator工具,设计了一个基于FPGA的多进制QAM调制器,在给出了系统设计框图后,重点介绍了扰码器、差分编码器、星座映射单元、nR成形滤波器等模块的设计方法,实现了64QAM的基带调制和中频处理,最终在FPGA上予以实现.
