Abstract:
This invention presents a method and apparatus for vertical layered finite alphabet iterative decoding of low-density parity-check codes (LDPC) which operate on parity check matrices that consist of blocks of sub-matrices. The iterative decoding involves passing messages between variable nodes and check nodes of the Tanner graph that associated with one or more sub-matrices constitute decoding blocks, and the messages belong to a finite alphabet. Various embodiments for the method and apparatus of the invention are presented that can achieve very high throughputs with low hardware resource usage and power.

Claim (Index 27):
The apparatus of  claim 12 , wherein each check node processor in the decoding loop module comprises:\n a single memory unit that is used to store the syndrome bits of the check nodes, which is accessed for updating the syndrome bits and generating the signs of the output messages of the check node processor; and a single memory unit that is used to store the magnitude states of the check nodes, wherein a magnitude state of a check node consists of a plurality of magnitudes of the incoming messages along with their respective edge indices, and wherein the memory unit is accessed for updating the magnitude states of the check nodes and generating the magnitudes of the output messages of the check node processor.
