Color Image Compression with Modified Fractal Coding on Spiral Architecture
—The proposed approach (CICMFCSA), firstly, compose the one-plane image using the pixel’s trichromatic coefficients. One-plane image in traditional square structure is represen...

Performance Analysis of Full-rate STBCs from Coordinate Interleaved Orthogonal Designs
— In this paper, we derive the theoretical symbol error rate (SER) for a full-rate space-time block coded (STBCed) system with coordinate interleaved orthogonal designs (CIODs) o...
