描述了一些新的短约束长度编码,用于卫星信道,这些信道是恒定包络,其频谱和能量效率介于其他最新编码技术之间,即r = 2/3编码8-PSK和r = 3/4编码16-PSK。我们使用两个8-PSK传输间隔来形成r = 5/6格码的调制基。一个特别吸引人的设计是一个八状态码,在高斯信道上产生6.2 dB增益,而不是未编码的8-PSK,但频谱效率仅牺牲16%。
Some new short constraint length codes are described for satellite channels which are constant-envelope and which have spectral and energy efficiencies intermediate to other recent coded techniques, namely r = 2/3 coded 8-PSK and r = 3/4 coded 16-PSK. We use two intervals of 8-PSK transmission to form a modulation base for r = 5/6 trellis codes. A particularly attractive design is an eight-state code, producing 6.2 dB gain on the Gaussian channel over uncoded 8-PSK, yet sacrificing only 16 percent in spectral efficiency.
