Interface-aware LDPC codes for millimeter wave communication systems

Millimeter wave communication is a main solution for the high speed backhaul and ultra-high speed access transmission. This paper presented the interface-aware LDPC codes in the millimeter-wave system to support highspeed Ethernet interfaces and reduce the conversion delay. Considering constraints of the encoded codeword length of 1 G to 100 G Ethernet physical layer, LDPC (196, 120), LDPC (588, 528), LDPC (1197, 1089) codes on the basis of 1 G, 10 G and 100G Ethernet interface were designed to reach low latency in the channel coding process. The simulation results claimed that the interface-aware LDPC codes have an excellent performance and the minimum processing delay in the system, taking encoding delay and decoding delay into consideration. The encoding delay of 0.58 - 1.17 us and the decoding delay of 3.20 - 4.26 us could meet the code rate for the different channels in Ethernet interfaces.
