Data and Image Transmission on DS-PAM UWB System in Parallel Links AWGN Channel Using Multiple Description Coding (MDC)
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2014, Vol 8, Issue 6
Abstract
UWB communication system is a new high performance technique with low power consumption which it has a large application for very high data rates in wireless telecommunications.In this paper, we consider image transmission in UWB system with parallel links AWGN noise channel using multiple description coding (MDC) technique. This idea is new, and so far there is no record of it. First, direct sequence ultra wide band performance techniques are analyzed for AWGN channels. Image transmission is then implemented with multiple description coding and with no multiple descriptions coding of image.The method of multiple description coding ensures thatthe version that the loss does not need to retransmit the missing versionand 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.
