What are regular LDPC codes?

What are regular LDPC codes?

LDPC codes are linear block codes, based on low-density parity check matrices H, i.e the number of non-zero elements in the matrix is much less than the number of zeros. The code rate R of an LDPC code is given by:(1) R = N – M N where N and M are respectively the number of columns and rows of H.

What is trapping set?

The sets most often used to take these animals are the dirthole set, the flat set, and the cubby set. One of the most important considerations inland trapping is covering the trap and bait. This helps keep birds of prey from spotting the bait and getting in the trap.

Are LDPC codes systematic?

LDPC are randomly generated and by nature, they are non-systematic codes.

Is LDPC a convolutional code?

The convolutional counterparts of LDPC block codes are LDPC convolutional codes. Analogous to LDPC block codes, LDPC convolutional codes are defined by sparse parity-check matrices, which allow them to be decoded using iterative mes- sage-passing algorithms.

What is a pocket set trapping?

Water trapping raccoons using a pocket set is probably the easiest and most effective way to trap a raccoon along a stream or river. The set is quick and easy to make, plus you have the ability to catch additional furbearers like mink and muskrats who also find the set irresistible. Raccoons are not trap shy animals.

What is a pocket set?

The Pocket set is a hole dug back into the bank a foot or more deep and three to eight inches wide and high. The hole is dug so that there is an inch or two of water in the hole. At the rear of the hole, there is a shelf that is out of the water. This shelf is used for placing bait or lure on.

How many bits can LDPC correct?

Ignoring any lines going out of the picture, there are eight possible six-bit strings corresponding to valid codewords: (i.e., 000000, 011001, 110010, 101011, 111100, 100101, 001110, 010111).

What is LDPC error correction?

In information theory, a low-density parity-check (LDPC) code is a linear error correcting code, a method of transmitting a message over a noisy transmission channel. An LDPC is constructed using a sparse Tanner graph (subclass of the bipartite graph).
