Block Turbo Code with Binary Input for Improving Quality of Service

An iterative decoding algorithm (“Block Turbo Code (BTC) algorithm”) for product codes based on soft decoding and soft decision output of the component codes was introduced by R. Pyndiah in 1994 [1][2]. It uses the concepts developed by C. Berrou who proposed a technique to encode and decode a class of error correcting codes, called “Turbo codes” CTC [3]. The BTC is based on the product code which is a series concatenated coding scheme, introduced by Elias [4]. The information bits are placed in a matrix. The rows of the matrix are encoded by a linear block code and the columns by a second block code.
