Turbo Decoder Applications
DVB-NGH is a draft standard for digital broadcasting systems for handheld devices. Parts of the standards are similar to DVB-T2-Lite. Hence, the maximum block length of the LDPC codes is 16200 bits. Seven new LDPC codes were added to the DVB family of standards (16200 bit codewords with rates 4/15, 7/15, 8/15, 9/15; 4320 bit codewords with rates 1/5 and 1/2, 8640 bit codeword with rate 1/4). All other codes have been used before, e.g., in DVB-S2.
DVB-NGH uses two LDPC codes (4320 bits, rate 1/5 and 8640 bits, rate 1/2) for signalling the current configuration of the DVB-NGH system. The 8640 bits code is an extended LDPC code based on a code with 4320 bits and rate 1/2.
