  Abstract

In this paper, we propose a new scheme to improve the performance of the existing Display Field Communication (DFC) in which a display and a camera are operating as a transmitter and a receiver, respectively. In the proposed scheme, we adopt the Discrete Cosine Transform (DCT) to transform an image into a spectral domain. In addition, Addition allocator and Subtraction data retrieval techniques are used to reduce the computational complexity when embedding data into an image. By appropriately adjusting the power of the embedded data through power allocation scheme, we prove that we can improve the overall performance of the proposed scheme based on numerical simulations.
