3.14 Low-density Parity Check (LDPC) Encoding
Lite implies LDPC as the FEC coding method which can correct bit error during trans-
mission. It allows the system to survive in poor SNR scenario. In the same SNR sce-
nario, it may allow the system to work in higher modulation scheme or have a better
packet error performance.
Lite supports 1/2, 2/3, 3/4, 5/6 LDPC encoding combined with different modulation
schemes, to meet different SNR and throughput requirement.
