Progressive Image Transmission over OFDM System with Minimum Peak to Average Power Ratio (PAPR)

N. D. Pergad 1, Ashok M Misal.

The main aim of this project is reduce the PAPR of transmitted OFDM signals, improve the transmitted image quality & The SPIHT coder is chosen as the source coding technique due to its flexibility of code rate and simplicity of designing optimal system. Trigonometric transforms are used in this scheme for improving the performance of the OFDM system and reducing the Peak-to-Average Power Ratio (PAPR) of OFDM signal. The PAPR is a major drawback of multicarrier transmission system such as OFDM. The Set Partitioning In Hierarchical Tress (SPIHT) algorithm is used for source coding of the images to be transmitted.
