komm.ConvolutionalStreamEncoder

Convolutional stream encoder. Encode a bit stream using a given convolutional code. The internal state of the encoder is maintained across each call.

Attributes:

• convolutional_code (ConvolutionalCode) –

  The convolutional code.

• state (int) –

  The current state of the encoder. The default value is 0.

Input:

• in0 (Array1D[int]) –

  The bit sequence to be encoded.

Output:

• out0 (Array1D[int]) –

  The encoded bit sequence.

Examples:

>>> convolutional_code = komm.ConvolutionalCode([[0o7, 0o5]])
>>> convolutional_encoder = komm.ConvolutionalStreamEncoder(convolutional_code)
>>> convolutional_encoder([1, 1, 1, 1])
array([1, 1, 0, 1, 1, 0, 1, 0])
>>> convolutional_encoder([1, 1, 1, 1])
array([1, 0, 1, 0, 1, 0, 1, 0])
