摘要

提出了一种有效的实时数字正交解调算法。它可以用一对正交高通有限脉冲响应滤波器和抽取器来实现。滤波器是通过使用适当的转换从一个四分之一带低通滤波器原型导出的。讨论了利用VLSI技术实现该算法的方法。

A wide bandwidth digital quadrature demodulator for electronic warfare receivers

An efficient algorithm for real-time digital quadrature demodulation is presented. It can be implemented with a pair of quadrature highpass finite impulse response filters and decimators. The filters are derived from a quarter-band lowpass filter prototype through the use of appropriate transformations. The implementation of the algorithm using VLSI technology is discussed.<>
