Abstract

Introducing multiple transceiver antennas in this generation of wireless systems, actually occurrences of image and video communication are begin to be often, as very high data rates begin to be serviceable with advanced and updated data reliableness. Imminent joint transmission and coding schemes that gives favorable multiple antenna systems matched with source informatics are begin to be applied. Based on this course of action, we can implement an unequal power allocation technique for transmission of enhancing images over MIMO (multiple-input multiple-output) systems. A video is divided into different frames i.e. images, and those images divided into different layers are transmitted concurrently from various transmit antennas using unequal transmit power, Results present that unequal power allocation technique gives significant image quality improvement as compared to different equal power allocations schemes. And this technique prevents distortion of images and videos.
