时频编码分集是对流层散射通信的一种重要体制。本文讨论了参数选择的原则和生成矩阵的求法,从而导出了通用的编码方法,得出了几种实际的編码方案,并用计算机算出了这些方案的全部码组。
Time-frequency code diversity is an important system of tropospheric scatter communications. In this paper, the principle of parameter selection and the algorithm of generator matrix are discussed. The general coding methods are derived and several actual coding schemes are obtained. All codes of these schemes are computed by computer.
