H.264/AVC is the most powerful technology in video compression/transmission area because of its high coding efficiency and robustness. In this paper, we propose a new hardware architecture of 8x8 integer transform and quantization for H.264 which promises very low resource utilization. In the architecture, each pixel is processed one by one on a simplified(More)
In this paper, we present a prototype FPGA design for an efficient physical layer implementation of a MIMO-OFDM technique. We propose a pipelined architecture using a Fast Fourier Transform that is shared across modulations for the system. Our experimental results show that the proposed implementation saves at least 30 percent of the hardware resources,(More)

In this paper, we introduce a new approach for image quality assessment. The proposed method estimates similarity of frequency between a distorted image and a reference image using 8×8 block based DCT. Different from existing method such as SSIM (Structural Similarity Index Method) and PSNR, it does not use any data such as intensity, mean, variance,(More)
