Parallel concatenation refers to a coding technique where two or more convolutional encoders are connected in such a way that the outputs of each encoder are interleaved. This method enhances error correction performance by allowing the encoded data to spread across multiple codewords, effectively leveraging the benefits of each individual encoder while creating a combined code that can approach the Shannon limit. This technique is particularly significant in the design of advanced error-correcting codes.
congrats on reading the definition of parallel concatenation. now let's actually learn it.
