An insight to the 1 lattice decoder for flat-fading multiple antenna wireless communications systems is presented in this paper. In particular, we show that by formulating the problem as a bounded error subset selection, the equivalent decoder finds the nearest lattice point to the received signal in the 1 sense. The search for the nearest lattice point is bounded inside a hypercube centered at the received vector;where the dimensions and orientation of the hypercube depends on the channel conditions. The search for the nearest codeword to the received vector is achieved by modeling the problem as a Mixed Integer Linear Program. The proposed decoder achieves near-optimum performance while its complexity is invariant with the operating signal to noise ratio.
Higher temperature induced by higher power density results in higher cost, lower performance and lower reliability. The thermal effects become important issues of today's VLSI design. In this paper, we adopt a RC-...

MPI is the traditional paradigm to parallelize applications for High Performance Computing environments. AzequiaMPI is an implementation of the MPI-1.3 standard. Its thread-based architecture enables it to run on high-end HPC machines as well as on embedded environments as soft-core processor in FPGAs. This article describes the experience of building a maintainable cluster of fourteen popular Xilinx XUP2-Pro FPGA development boards around the PetaLinux/Micro blaze base. Figures on the AzequiaMPI performance are given.
