Image transmission through wireless channel: A review

Developing an efficient wireless communication system for image and video signals other than voice signal is the need for a mobile radio link. Image transmission through a wireless channel requires an image to be compatible with the channel characteristics such as bandwidth. The image and video signals occupies a large space in storage device and takes long time to transmit over a wireless channel. Compression techniques are used to reduce the redundant data from an acquired image and make it compatible with channel bandwidth. In this paper various compression techniques and communication models are analyzed. Various noises introduced during image acquisition and in channel. These noises are required to be reduced during image formatting and de-formatting process at transmitter and receiver respectively.
