A Novel Variation on Non Local Means Algorithm for Denoising of Contrast-Enhanced MR Images
Abstract
liedE � ht��U�oH) convolutional codes and compared with the (2,1,7) convolutional codes. The proposed interleaver is applied to different bits stream lengths of 1024, 2048, 4096, 8192, and 16384 bits. The simulation results show the superiority of the proposed chaotic interleaved convolutional codes scheme over the traditional schemes in the image transmission over the mobile channels with respect the shorter constraint length of the encoder. Also, the chaotic interleaver performs better with the packet length increasing. The chaotic interleaver enhances the security with the different secret key for every transmitted packet. The computer simulations are carried out using the widely accepted Jakes’ model. The results reveal that the proposed scenarios can be applied to the long bit stream packets technologies such as Wimax.
