Image Transmission Using Adaptive Channel Coding for Electronic Toll Collection System
Rama Krishna Reddy · 2011
With the rapid growth of wireless communication systems there is an increasing demand for efficient image transmission. In Electronic Toll Collection System (ETC) the violation enforcement team should get an image of traveller’s number plate from Toll Plaza point for tracking the traveller’s information to inform travellers about their toll fee. Combined source-channel coding approach is described for the encoding, transmission and remote reconstruction of image data. More specifically, a combined source-channel coding approach is necessary in optimally allocating rate between source and channel coding subject to a fixed Constraint on overall transmission bandwidth. In this paper the source-channel coding is implemented using Lab view. The results for specific source and channel coding schemes show marked improvement over suboptimum choices of channel error protection. In addition, the results approach information-theoretic performance bounds which are developed in this work.
