This thesis is concerned with a number of novel uses of spatial coupling, applied to a class of probabilistic graphical models. These models include error correcting codes, random constraint satisfaction problems (CSPs) and statistical physics models calle ...
Approximation circuits offer superior performance (speed and area) compared to traditional circuits at the cost of computational accuracy. The accuracy of the results in approximation circuits is evaluated based on several error metrics such as worst-case ...
We report the highest performance 640-Gb/s transmitter and receiver, based on cavity-less pulse generation and a novel sampling receiver constructed using a single fiber parametric gate capable of self-tracked 40-Gb/s tributary extraction. The performance ...

Conducting a thorough performance evaluation of an STM is very time consuming. Depressingly, even with all this effort, and even with the same application, it can still be hard to predict the performance if the number of underlying threads on which the app ...
The implementation of a digital four-level pulse-amplitude-modulation reduced-state sliding-block Viterbi detector (VD) with two substates and two embedded per-survivor decision-feedback taps operating at one-eighth of the modulation rate is described. Imp ...

Using a transformation based, at least in part, on a non-simple orthogonal matrix, data may be transmitted over a data bus in a manner that is resilient to one or more types of signal noise, that does not require a common reference at the transmission and ...
Affine rank minimization algorithms typically rely on calculating the gradient of a data error followed by a singular value decomposition at every iteration. Because these two steps are expensive, heuristics are often used for approximations that reduce co ...
The power system has been used for communication purposes for many decades, although it was mainly the power utility companies that used low bit rates for control and monitoring purposes. In the last ten years, however, the deregulation of the power and te ...
Underwater communications is a very challenging topic due to its singular channel characteristics. Most protocols used in terrestrial wireless communications can not be directly applied in the underwater world. A high bit error rate and low propagation del ...

Recently, a world’s first ever power electronic traction transformer (PETT) for 15 kV, 16 2 /3Hz railway grid, has been newly developed, commissioned, and installed on the locomotive, where it is presently in use. This marks an important milestone in the t ...
