Examples of 'convolutional code' in a sentence
Meaning of "convolutional code"
Convolutional code: In the context of coding theory and telecommunications, a convolutional code is a type of error-correcting code where encoding is done by convolving the input data with the code's impulse response. This results in a coded sequence that can be used to detect and correct errors during transmission
