Cooperative Transmission Scheme to Increase Gain by Using STBC
— Multiple-Input Multiple-Output (MIMO) systems are composed of source and destination nodes with multiple antennas. But, when nodes cannot support multiple antennas due to size ...

Transmit Precoding for the Multiple Antenna Broadcast Channel
— In this paper we compare the following two methods of transmit precoding for the multiple antenna broadcast channel: vector perturbation applied to channel inversion (also term...

High-rate, Multi-Symbol-Decodable STBCs from Clifford Algebras
It is well known that Space-Time Block Codes (STBCs) obtained from Orthogonal Designs (ODs) are singlesymbol-decodable (SSD) and from Quasi-Orthogonal Designs (QODs) are double-sy...

Performance and Scalability Analysis of Cray X1 Vectorization and Multistreaming Optimization
Cray X1 Fortran and C/C++ compilers provide a number of loop transformations, notably vectorization and multistreaming, in order to exploit the multistreaming processor (MSP) hard...

Multigroup-Decodable STBCs from Clifford Algebras
A Space-Time Block Code (STBC) in K symbols (variables) is called g-group decodable STBC if its maximumlikelihood decoding metric can be written as a sum of g terms such that each ...
