The invention discloses an underwater acoustic sparse channel estimation variable step sparsity adaptive matching tracking method, which fully utilizes the underwater acoustic channel sparse multipathcharacteristic and avoids the waste of frequency spectrum resources caused by the excessive number of pilots in the traditional channel estimation technology. The method does not need sparseness as apriori information, and the size of the support set is the estimated sparseness at the end of iteration by expanding the support set through step size. In addition, the signal reconstruction processis divided into several stages by combining stage idea and variable step size, the number of atoms in the support set in a certain phase remains constant, and the adjacent phases gradually expand thesupport set by different step sizes. The invention improves the recovery accuracy on the premise of not significantly increasing the calculation amount, that is, obtains a better trade-off between thereconstruction accuracy and the calculation complexity. Compared with the prior classical greedy algorithm, the invention does not need sparseness as a prior information, and the step size adaptive change can give consideration to the algorithm accuracy and the operation efficiency.

Disclosed is an effective high-speed encoding method using a parity-check matrix proposed in an IEEE 802.1x standard for high-speed low-density parity-check encoding. In the prior art, encoding was performed by blocking and dividing the parity-check matrix of the LDPC code and through relevant matrix equations, or encoding was performed by an encoding apparatus that divides a matrix multiplication operation of a generated matrix acquired by using an arbitrary parity-check matrix of a quasi-cyclic (QC) LDPC code and information vectors into two sequential steps and implements each step as a cyclic shift-register. Unlike the prior art, the present invention provides an effective high-speed encoding method having low additional complexity by using a quasi-cyclic characteristic of a parity-check matrix as well as an encoding method through generation of a temporary parity bit, generation of a correction bit, and correction of a parity bit by using the parity-check matrix having a dual-diagonal parity structure proposed in the standard.
