For communication designers, especially those in the networking and wireless field, the Shannon limit can be seen as the Holy Grail. And, since being first defined in ...

Last month I showed how coding and error correction allows next-generation broadcast technologies such as DVB-T2 and DVB-NGH to achieve performance very close to the ...

Low-density parity-check (LDPC) codes represent one of the most effective error-correcting schemes available, approaching Shannon’s theoretical limit whilst maintaining a relatively low decoding ...

A new technique for efficient encoding of LDPC codes based on the known concept of Approximate Lower Triangulation (ALT) is introduced. The greedy permutation algorithm is presented to transform ...

January 6, 2025 - Global IP Core Sales - In the Sum Product Algorithm (SPA) for LDPC decoding the messages are sent from the check nodes to bit nodes after the SPA steps which are (for one iteration): ...

What does satellite communication and flash storage have in common? They are error prone and low density parity check (LDPC) code technology is the answer to the ...
