due to damaging effects of speckle noise to information of radar images, reduction of these effects has been considered by many researchers. we discussed speckle reduction of radar images based on curvelet transformation. more specifically we discussed the speckle reduction with emphasizing on preservation of the edges by hard thresholding of curvelet transformation. in this algorithm, first mu...

Transmission of high data rate over multipath environment is associated with many wireless applications. However, this transmission results in delay which leads to ISI distortion and causes error. The existing LE MIMO systems such as ZF equalizer used addressing problem reduces the completely but noise amplification. Likewise, MMSE only cannot eliminate ISI. Therefore, paper proposed a hybrid f...
