Search Based Weighted Multi-Bit Flipping Algorithm for High-Performance Low-Complexity Decoding of LDPC Codes
In this paper, two new hybrid algorithms are proposed for decoding Low Density Parity Check (LDPC) codes. Original version of the proposed algorithms named Search Based Weighted Multi Bit Flipping (SWMBF). The main idea of these algorithms is flipping variable multi bits in each iteration, change in which leads to the syndrome vector with least hamming weight. To achieve this, the proposed algo...

متن کاملDesign of Enhanced Multi-bit Threshold Bit Flipping Algorithm for Low Complex Ldpc Decoders
Communication is transfer of information from source to sink or sender to receiver. The signal when transferred through the noisy channel gets affected by the noise and becomes an error signal when it reaches the receiver. Decoding is the process of retrieving the correct information from the received signal. The weighted bit flipping LDPC decoding algorithm gives a good performance in retrievi...
متن کاملCheck Reliability Based Bit-Flipping Decoding Algorithms for LDPC Codes
We introduce new reliability definitions for bit and check nodes. Maximizing global reliability, which is the sum reliability of all bit nodes, is shown to be equivalent to minimizing a decoding metric which is closely related to the maximum likelihood decoding metric. We then propose novel bit-flipping (BF) decoding algorithms that take into account the check node reliability. Both hard-decisi...
متن کاملDecoding LDPC codes via Noisy Gradient Descent Bit-Flipping with Re-Decoding
In this paper, we consider the performance of the Noisy Gradient Descent Bit Flipping (NGDBF) algorithm under re-decoding of failed frames. NGDBF is a recent algorithm that uses a non-deterministic gradient descent search to decode lowdensity parity check (LDPC) codes. The proposed re-decode procedure obtains improved performance because the perturbations are independent at each re-decoding pha...
