Ldpc circuit


(LDPC) application with a novel charge-recovery logic called pseudo-NMOS boost logic (pNBL), to achieve high-speed and low power dissipation. pNBL is a high-overdriven and low area consuming charge recovery logic, which belongs to boost logic family. Proposed Processing Engine is used in LDPC circuit Although the LDPC can approach the Shannon limit, it would affect the subsequent circuit design if it is not properly encoded. Since the number of “1” in the H matrix is much smaller than the number of “0”, it is called a low density matrix.

Proposed Processing Engine is used in LDPC circuit DVB-S2X (LDPC) DVB-S2X is the extension of the popular DVB-S2 satellite standard. Improvements including additional codes, higher modulations (64/128/256APSK) and smaller roll-off factors improve the efficiency by 51% over DVB-S2. Survey of Turbo, LDPC, and Polar Decoder ASIC Implementations. Abstract: Channel coding may be viewed as the best-informed and most potent component of cellular communication systems, which is used for correcting the transmission errors inflicted by noise, interference, and fading.
