Computex 2014 - Error rates are increasing as NAND manufacturers shrink lithography. This requires SSD controller innovation to provide stronger error correction ...
For communication designers, especially those in the networking and wireless field, the Shannon limit can be seen as the Holy Grail. And, since being first defined in ...
def simulate_ldpc_erasure_correction(erasure_thresholds, n, d_v, d_c, snr_db=10, num_iterations=1000, plot_interval=1000, verbose=False): Simulate LDPC encoding ...
Abstract: Previous examples of probabilistic amplitude shaping (PAS) for low-density parity-check (LDPC) codes use protographs that lack the structure that facilitates low-complexity encoding. This ...
Abstract: We propose an efficient encoding algorithm and architecture for 2-D quasi-cyclic (QC) low-density parity-check (LDPC) codes. The encoding algorithm is derived based on the null space of the ...
A new technique for efficient encoding of LDPC codes based on the known concept of Approximate Lower Triangulation (ALT) is introduced. The greedy permutation algorithm is presented to transform ...
Our LDPC encoding and decoding IP for the 3GPP New Radio uplink and downlink data channel includes the entire processing chain, to provide quick and e ...
