What does LDPC mean? In information theory, a low-density parity-check (LDPC) code is a linear error correcting code, a method of transmitting a message over a noisy transmission channel.
What is LDPC in WIFI? LDPC is a forward-error-correction coding scheme used to ensure high coding reliability and increase coding gain. Invented in the early 1960s, the code can transmit messages through frequencies experiencing a great deal of background or data-corrupting noise.
What is LDPC coding in 5G? Low-Density Parity- Check (LDPC) codes are linear error-correcting codes. According to the 3rd Generation Partnership Project (3GPP) TS 38.212, LDPC is recommended for the Fifth-generation (5G) New Radio (NR) shared channels due to its high throughput, low latency, low decoding complexity and rate compatibility.
How does LDPC work? Decoding of LDPC Codes
If any bit is contained in more than a fixed number of unsatisfied parity equations, the value of that bit is reversed. Once the new values are obtained, parity equations are recomputed using the new values. The procedure is repeated until all the parity equations are satisfied.
