| 摘 要： | 本文介绍了一种实现数字调相系统模拟信号源的新方法,即PSK信号波形存贮法.其原理是利用EP ROM直接存贮需要传输的信号波形序列,系统运行时从EP ROM中读出并获得所需要的PSK信号.该方法具有很高的数据传输速率,并可以在很宽的范围内任意选择.在设计PSK或DPSK模拟信号源中获得广泛应用.

| Abstract: | A new approach to realizing the analog signal source for digital phase modulation, or the approach to storing PSK signal waves, is described. The concept consists in utilizing EP ROM to store signal waves to be transmitted. During operation, the PSK signal is obtained by reading from EP ROM. The new method is characterized by a higher transmitting rate and an arbitrary selection of the rate within a wide range. |
