相对移相(DPSK)信号的数字式解调器近些年来已逐渐引起人们的重视,由于它具有易于集成、易于生产等优点,必将在数字传输设备中广泛采用。本文详细地讨论了四种数字式解调器的基本原理及实现方法。理论分析和实际测试都表明,数字式解调器具有良好的性能。
The digital demodulator of relative phase shift (DPSK) signal has drawn more and more attention in recent years. It is bound to be widely used in digital transmission equipment due to its advantages of easy integration, easy production and so on. This article discusses in detail the basic principles and implementation methods of four digital demodulators. Theoretical analysis and practical tests have shown that the digital demodulator has good performance.
