反馈信道的存在使得各种顺序传输过程成为可能，根据信息在有噪声的前向信道上编码传输的方式，每个过程都可以被分类为块传输或连续传输方案。描述了一种采用二进制对称前向信道（但适用于任何离散无记忆前向信道）和无噪声反馈信道的顺序连续传输系统。在低于信道容量的所有传输速率下，其错误指数大大大于最佳块码错误指数。并给出了在IBM 709计算机上模拟得到的有效约束长度的平均值和一阶概率分布。
The presence of a feedback channel makes possible a variety of sequential transmission procedures, each of which can be classified as either a block-transmission or a continuous-transmission scheme according to the way in which information is encoded for transmission over a noisy forward channel. A sequential continuous-transmission system employing a binary symmetric forward channel (but which is suitable for use with any discrete memoryless forward channel) and a noiseless feedback channel is described. Its error exponent is shown to be substantially greater than the optimum block-code error exponent at all transmission rates less than channel capacity. The average value and the first-order probability distribution of the effective constraint length, found by simulating the system on an IBM 709 computer, are also given.
