چکیده

UWB communication system is a new high performance technique with low power consumption which has a large application for very high data rates in wireless telecommunications. In this paper, the image transfer techniques using MIMO-UWB wireless environment is introduced in MDC deals. This idea is new and so far that there is no record of it. First, direct sequence ultra wide band performance techniques are analyzed for channels fading. Image transmission is then implemented with multiple description coding and with no multiple descriptions coding of image. The method of multiple description coding ensures that the version that the loss does not need to retransmit the missing version and acceptable quality of image obtain against the channel errors. Send a picture of the proposed system with different number of transmitter and receiver antennas have been numerous experiments confirm the success of the method. Experimental results show that the desired goals are reached.
