Probabilistic shaping for intensity modulation and direct detection (IM/DD) links is discussed a peak power constraint determined by the limited extinction ratio (ER) of optical modulators introduced.

We present a multiple-voltage high-level synthesis methodology that minimizes power dissipation of VLSI signal processing. By applying algorithmic transformations, the proposed approach optimizes the power saving, in terms of the average power and peak power, for DSP applications when the resources and the latency are constrained. Our approach is motivated by the maximization of task mobilities...

In this paper we explore the tradeoff between the leakage power and fan power to dynamically migrate tasks to minimize the overall power consumption in a homogeneous many-core processor. Our analysis shows that the overall power can be minimized if a task allocation for minimum peak temperature is adopted together with an intelligent fan speed adjustment that finds the optimal tradeoff between ...

The arbitrarily varying channel (AVC) can be interpreted as a model of a channel jammed by an intelligent and unpredictable adversary. We investigate the asymptotic reliability of optimal random block codes on Gaussian arbitrarily varying channels (GAVC’s). A GAVC is a discrete-time memoryless Gaussian channel with input power constraint PT and noise power N,, which is further corrupted by an a...

New measures of peak power are proposed in the context of sequential circuits, and an efficient automatic procedure is presented to obtain very good lower bounds on these measures, as well as providing the actual input vectors that attain such bounds. Automatic generation of a functional vector loop for near-worst case power consumption is also attained. Experiments show that vector sequences g...

This paper derives upper and lower bounds on the capacity of the multipleinput single-output free-space optical intensity channel with signal-independent additive Gaussian noise subject to both an average-intensity and a peak-intensity constraint. In the limit where the signal-to-noise ratio (SNR) tends to infinity, the asymptotic capacity is specified, while in the limit where the SNR tends to...

Several recent studies have provided evidence that individual lighting control results in occupant satisfaction benefits. As part of a larger series of pilot studies, we examined the use of individual controls under various lighting power constraints. The studies took place in a mock-up open-plan office space, in which participants spent around two hours doing typical office tasks and answering...

This paper investigates the capacity and capacity per unit cost of Gaussian multiple-access channel (GMAC) with peak power constraints. We first devise an approach based on Blahut-Arimoto Algorithm to numerically optimize the sum rate and quantify the corresponding input distributions. The results reveal that in the case with identical peak power constraints, the user with higher SNR is to have...

Battery Energy Storage System (BESS) can be utilized to shave the peak load in power systems and thus defer the need to upgrade the power grid. Based on a rolling load forecasting method, along with the peak load reduction requirements in reality, at the planning level, we propose a BESS capacity planning model for peak and load shaving problem. At the operational level, we consider the optimal...
