MATLAB结构包含卷积编码器的格子描述。

在Continuousmode (default setting), the block retains the encoder states at the end of each frame, for use with the next frame.

在截断（每个帧重置）mode, the block treats each frame independently. I.e., the encoder states are reset to all-zeros state at the start of each frame.

在通过附加位终止格子mode, the block treats each frame independently. For each input frame, extra bits are used to set the encoder states to all-zeros state at the end of the frame. The output length is given by $$y=n\cdot (x+s)/k$$, wherex是输入位的数量，并且 $$s=\text{constraint length}-1$$（或者，在多个约束长度的情况下，s=sum（约束级（i）-1））。该块为列矢量输入信号万博1manbetx支持此模式。

在Reset on nonzero input via portmode, the block has an additional input port, labeledRst。When theRstinput is nonzero, the encoder resets to the all-zeros state.

信号星座中的点数。

块的输出类型可以指定为single或者double。By default, the block sets this todouble。
