Ahmet Inan	717d482822	shuffle codeword for SIMD aligned memory access ... Idea taken from: Low cost LDPC decoder for DVB-S2 by John Dielissen, Andries Hekstra and Vincent Berg - 2006	2019-09-23 12:00:06 +02:00

Ahmet Inan	86bf81dd2d	got rid of some modulo operations	2018-12-15 17:09:03 +01:00
Ahmet Inan	4e39392acf	only need first q entries	2018-12-15 15:05:19 +01:00
Ahmet Inan	ce9674883c	flattened first parity handling	2018-12-15 12:12:56 +01:00
Ahmet Inan	584f6c0d9d	use max value for fake parity bit to stay on the safe side	2018-12-14 20:42:25 +01:00
Ahmet Inan	3060e82da6	got rid of exclusive_reduce	2018-12-13 13:23:41 +01:00
Ahmet Inan	3e881ce049	accelerate decoder using SIMD ... Also added a fake parity bit to reduce code duplication. The fake parity bit seems not to affect the decoding performance.	2018-12-13 11:21:58 +01:00
Ahmet Inan	199a988def	added LDPC encoder and layered decoder ... lifted from my LDPC project: https://github.com/xdsopl/LDPC	2018-12-13 11:19:31 +01:00
