This paper examines the applicability of the genetic algorithm (GA) to generation of nonbinary low-density parity-check (LDPC) codes over GF(q) which is suitable for distributed video coding (DVC). Error probability distribution in side-information of the DVC is approximated by Gaussian and Laplace distributions, and then a fitness of an LDPC matrix is defined under this approximation. The GA is designed...
This paper highlight the performance analysis of BPSK and QPSK using error correcting code. To calculate the bit error rate, different types of error correcting code were used through an Additive White Gaussian Noise (AWGN) channel. Bose-Chaudhuri-Hocquenghem (BCH), Cyclic code and hamming code were used as the encoder/decoder technique. Basically, the performance was determined in term of bit rate...
This paper presents multibit error-correction schemes for nor Flash used specifically for execute-in-place applications. As architectures advance to accommodate more bits/cell and geometries decrease to structures that are smaller than 32 nm, single-bit error-correction codes (ECCs) are unable to compensate for the increasing array bit error rates, making it imperative to use 2-b ECC. However, 2-b...
An iterative joint decoding algorithm for data gathering wireless sensor networks is proposed in where the correlation between sensorspsila data is considered as a global code and iterative decoding is performed by concatenating the global decoder with the decoder of error correcting code applied to encode sensors observations. We apply this algorithm for sensor networks with binary CEO model where...
