摘要

讨论了一种跳频ungerboeck编码的4路DPSK高频调制解调器的设计。首先，他们提出了一个通用的渠道模型。接下来，他们给出了8-ary和4-ary差分相干DPSK的速率-2/3编码的信道仿真结果。研究了加性高斯白噪声和瑞利衰落信道。阐述了跳频波形的基本结构，并说明了如何将Ungerboeck编码与该波形结合产生跳频编码调制>

A frequency-hopped Ungerboeck-encoded 4-ary DPSK modem

The authors discuss the design of a frequency-hopped Ungerboeck-encoded 4-ary DPSK HF modem. First, they present a general channel model. Next, they present channel simulation results for rate-2/3 encoding of 8-ary and 4-ary differentially coherent DPSK. Both additive Gaussian white noise and Rayleigh fading channels are examined. The basic structure of the frequency-hopped waveform is elucidated, and it is shown how the Ungerboeck encoding is combined with the waveform to produce the frequency-hopped encoded modulation.<>
