Section 6 concludes the paper. II. TURBO PRODUCT AND LDPC CODES. This section outlines the necessary background on TPC and LDPC codes used.
Performance curves of iterative coding schemes such as LDPC codes and turbo codes are well-known as “waterfall”. do exhibit error floors. Unlike parallel concatenated turbo codes, however, the error floor does not typically arise. gives the product (sum in the log-domain) of these two curves. It indicates the failure.

Error floor – Wikipedia – The error floor is a phenomenon encountered in modern iterated sparse graph- based error correcting codes like LDPC codes and turbo codes. When the bit error ratio (BER) is plotted for conventional codes like Reed–Solomon codes under algebraic decoding or for convolutional codes under Viterbi decoding, the BER.
