The technique that allows for researchers to read and convert the genetic information found in the DNA of any organisms is called Genome Sequencing. Genome Sequencing involves determining the order of the nucleotide subunits found in DNA, which consists of a small number of bases called short reads. The human genome is approximately 3 billion bases in length, which would take months or years to be...
Unlike other digital signal processing techniques such as the Fast Fourier Transform for one-dimensional (1D) and two-dimensional (2D) data (FFT1 and FFT2) that assume signal linearity and stationarity, the Hilbert-Huang Transform (HHT) utilizes relationships between arbitrary signal's local extrema to find the signal instantaneous spectral representation. This is done in two steps. Firstly, the Huang...
This work presents a static instruction allocation scheme for the precision timed architecture's (PRET) scratchpad memory. Since PRET provides timing instructions to control the temporal execution of programs, the objective of the allocation scheme is to ensure that the explicitly specified temporal requirements are met. Furthermore, this allocation incorporates instructions from multiple hardware...
This paper presents a VLSI architecture of a novel soft-output K-Best MIMO detector. The proposed detector attains low computational complexity using three improvement ideas: relevant discarded paths selection, last stage on-demand expansion, and relaxed LLR computation. A deeply pipelined architecture for a soft-output MIMO detector is implemented for a 4×4 64-QAM MIMO system realizing a peak throughput...
QR decomposition (QRD) is an essential signal processing task for many MIMO signal detection schemes. However, decomposition of complex MIMO channel matrices with large dimensions leads to high computational complexity, and hence results in either large core area or low throughput. Moreover, for mobile communication applications that involve fast-varying channels, it is required to perform QR decomposition...
Web services burst into the scene in 1998, with all the fanfare of "loosely coupled". For all its proponents, it has enjoyed only limited adoption within the enterprise. Enter Web 2.0 - the social revolution of the Internet. This duo, going by the moniker 'Global SOA', can turn enterprise wide web services for the end-user. Web Services Security Specification (WS-Security - OASIS) provides...
