The simulation of computer architecture is an important task in the development of new architectures. Exploring novel architectures requires simulations which are flexible, easy to produce, and high performance. The greater these characteristics, the more efficiently the design space can be explored. A number of simulation frameworks exist which can assist the architect in creating new simulato...

We develop a new switch-level simulator, CSim, for MOS transistor cells. CSim simulates cells without circuit parameters, such as the sizing of transistors. To tackle the challenges caused by the lack of circuit parameters, a new transistor-level levelization algorithm is developed. SPICE simulator is used as reference simulator, CSim is accurate in a sense that the simulation results for a cel...

There are many research and clinical settings in which accurate objective measures of speech intelligibility are either necessary or highly desirable. Unfortunately, most objective measures of intelligibility require blinded human listeners to classify speech tokens obtained from the talker whose speech intelligibility is to be measured, a process that can be both costly and time-consuming to c...

SUMMARY We propose a novel asynchronous direct-sequence code-division multiple access (DS-CDMA) using feedback-controlled spreading sequences (FCSSs) (FCSS/DS-CDMA). At the receiver of FCSS/DS-CDMA, the code-orthogonalizing filter (COF) produces a spreading sequence , and the receiver returns the spreading sequence to the transmitter. Then the transmitter uses the spreading sequence as its upda...

Multi-Carrier Code Division Multiple Access (MC-CDMA) is a modulation scheme that combines the advantages of OFDM and CDMA to provide robustness against frequency selectivity in wireless channels. Arrayed MC-CDMA systems combine MC-CDMA and antenna array technology to harness the spatial and temporal ’signatures’ of received signals, thus making it possible to realize high transmission rates en...
