一种高性能的数字预失真系统硬件设计与实现

A High-performance Hardware Design and Implementation for Digital Predistortion System

针对高频和宽带数字广播信号,设计了一种基于FPGA的数字预失真硬件系统,设计选用了高性能的数字和模拟器件,并重点考虑了高速硬件系统的电磁兼容和信号完整性的电路设计。工程实测证明了本预失真硬件系统的高性能,稳定性和可靠性。

This paper designs a digital predistortion hardware system based on FPGA for broadband and high-frequency radio signals. High performance digital and analog devices are selected for this predistor- tion hardware system, and furthermore, electromagnetic compatibility and signal integrity are carefully de- signed in its pcb design. Engineering measurements prove that this predistortion hardware system is of high performance, stability and reliability.
