In this paper, we present a low complexity Quasi-cyclic -low-density-parity-check (QC-LDPC) encoder hardware based on Richardson and Urbanke lowertriangular algorithm for IEEE 802.11n wireless LAN Standard for 648 block length and 1/2 code rate. The LDPC encoder hardware implementation works at 301.433MHz and it can process 12.12 Gbps throughput. We apply the concept of multiplication by consta...

A blind deconvolution algorithm based on the Richardson–Lucy deconvolution algorithm is presented. Its performance in the presence of noise is found to be superior to that of other blind deconvolution algorithms. Results are presented and compared with results obtained from implementation of a Weiner filter blind deconvolution algorithm. The algorithm is developed further to incorporate functio...

We describe a new family of weak p-th order accurate SDE time integration schemes, called the Direct Richardson p-th order accurate (DRp) schemes. The DRp schemes use the idea of Richardson extrapolation on Euler time steps, performed by way of an acceptance-rejection algorithm. Previous applications of Richardson extrapolation to the Euler scheme are applicable only when the objective is to es...

Image deconvolution is an effective image restoration technique to improve the quality of digital microscopic images resulting from out-of-focus blur. To solve the severely ill-posed problem of traditional Richardson–Lucy method, considering the point spread difference of various directions, a new microscope image restoration method based on multiple defocused images of different aperture is pr...
