LDPC Codes Construction and Performance Evaluation

Construction and Performance Evaluation of LDPC Codes over Finite Fields

• Broschiertes Buch

Produktbeschreibung

Low Density Parity Check (LDPC) codes are one of the block coding techniques that can approach the Shannon's limit within a fraction of a decibel for high block lengths. In many digital communication systems these codes have strong competitors of turbo codes for error control. LDPC codes performance depends on the excellent design of parity check matrix and many diverse research methods have been used by different study groups to evaluate the performance.Finite fields construction method is used and diverse techniques like masking, dispersion and array dispersion for the construction of parity check matrix H. These constructed codes are then simulated to make the performance evaluation. Simulation was done for different rates using additive white Gaussian noise (AWGN) channel. In MATLAB a library of different functions was created to perform the task for base matrix construction,dispersion,masking, generator matrix construction etc.
