摘      要：Table based error correction and decoding of rate one-half convolutional codes is described. A new class of fast-decodeable locally invertible convolutional coder based on a one-to-one mapping between information and encoded blocks of equal lengths is defined. The syndrome is used as an address to access a correction table which stores precomputed correction information, The correction table gen generation process is described and a specific table based correction algorithm is given. Performance of this scheme is analyzed and simulation results are presented.
