Construction analysis of low-density parity-check codes for free-space optical communication
Xiao Xuena, Xiao Xuena · 2010
In this paper, we study channel model of free-space optical communication and compare the various parity-check matrix construction of low-density parity check codes. Through the comparison of various parity-check matrix construction and the thinking to the influence from ring, we find a improved parity-check matrix construction of low-density parity check codes-л-rotated construction. Then we have a emulation analysis of construction capability between various parity-check matrix construction and π-rotated construction.
