High-rate, Double-Symbol-Decodable STBCs from Clifford Algebras
— For the number of transmit antennas N = 2a the maximum rate (in complex symbols per channel use) of all the Quasi-Orthogonal Designs (QODs) reported in the literature is a 2aâˆ...

The Orientation Adaptive Lapped Orthogonal Transform for Image Coding
In this paper, a lapped orthogonal transform adapted for local directionality of an image is proposed and its application in adaptive image coding is presented. First, we address ...

Reduced ML-Decoding Complexity, Full-Rate STBCs for $2^a$ Transmit Antenna Systems
— For an nt transmit, nr receive antenna system (nt × nr system), a full-rate space time block code (STBC) transmits nmin = min(nt, nr) complex symbols per channel use and in ge...
