摘要：Communication has always been on the rise especially when it comes to the transmission of video signals. The problems faced by video transmission include consumption of large bandwidth and video quality at the receiving side. This can be overcome by having a propervideo coding and proper control over the rate of transmission based on channel conditions. In our paper, we focus on these areas and present transmission control technique for wireless video transmission over UWB channel. In our technique, the major emphasis lies on the H.264 encoder and the use of fuzzy controller. The technique comprises of three modules, namely transmission module, control module and receiver module.Proposed technique is implemented using Matlab and the evaluation metrics used are BER and MSE. Comparative analysis is made by comparing our proposed technique to the SamiaShimuet al.[1] results. From the results, the net average BER came about 0.034 for the base compared to 0.032 for the proposed technique and net average MSE came about 117 for the base compared to 48.8 for the proposedtechnique. The obtained values show the effectiveness of the proposed technique by having lower MSE and BER values.
