Efficient Reconstruction of Hexagonally Sampled Data using Three-Directional Box-Splines
Three-directional box-splines are particularly well-suited to interpolate and approximate hexagonally sampled data. In this paper, we propose a computationally efficient end-toend...

Joint Frequency-Domain Differential Detection and Equalization for 2-Dimensional Spread/Chip-Interleaved DS-CDMA Uplink Transmis
—The multiple-access interference (MAI) limits the performance of the DS-CDMA uplink transmission. 2 dimensional (2D) spread/chip-interleaved DS-CDMA is an MAI-free system, where...
