LDPC Decoder Applications
The Chinese Mobile Multimedia Broadcasting (CMMB) standard was published in 2006 by the Chinese State Administration of Radio, Film, and Television (SARFT). The standard is intended for handheld devices and supports data rates of up to 16 Mbit/s.
Two LDPC codes are defined, both of the same block length. While in DVB-x2 an outer BCH decoder is applied, CMMB concatenates the LDPC decoder with an outer Reed-Solomon decoder. Each LDPC code can be concatenated with three diffferent RS-Codes of different rates. But it is also possible to omit the outer RS-Code.
