What is Block Turbo Code (BTC)?

A Block Turbo Code (BTC) is a linked block code, it is decoded with an iterative decoding method. There are serial and parallel concatenated codes. A serial concatenated code dependent on the possibility of 2-dimensional product code is known as Turbo Product Code. Block turbo code is quite the same as turbo codes dependent on iterative decoding of concatenated recursive convolutional codes.
