We propose an iterative design algorithm for jointly optimizing source and channel codes. The joint design combines channel-optimized vector quantization (COVQ) for the source code with rate-compatible punctured convolutional (RCPC) coding for the channel code. Our objective is to minimize the average end-to-end distortion. For a given channel SNR and transmission rate, our joint source and cha...

Transform coding (TC) is an efficient and effective vector quantization approach where the resulting compact representation can be the basis for a more elaborate hierarchical framework for sub-linear approximate search. However, as compared to the state-of-the-art product quantization methods, there is a significant performance gap in terms of matching accuracy. One of the main shortcomings of ...

In this paper, we propose a distinctive pilot power allocation algorithm to maximize the sum rate in multi-cell multi-user massive multiple-input multiple-output (MIMO) system. The optimizes powers by polarizing corresponding SINR values. order polarize SINRs, difference between average per cell and individual is calculated for each user of whole cells. exponential form used calculations weight...

According to the newly introduced water resources management in China, which is the most stringent thus far, pollution limits of water functional zones should be enhanced. In response to this recent change, we propose a provincial initial water rights incentive allocation model with total pollutant discharge constraint. Firstly, three objective functions are set up, namely the maximum comprehen...

pricing policies play an important role in water demand management and its optimal allocation. determining proper water price leads to optimal allocation of water especially in agricultural consumptions. applying new subsidy targeting law in iran which insists on pricing water based on its supply cost, will effects considerably on water resource management in agriculture sector. so, in this stu...

Hydroclimatic risks and adaptive capacity are not distributed evenly in large river basins of federal countries, where authority is divided across national and territorial governments. Transboundary river basins are a major test of federal systems of governance because key management roles exist at all levels. This paper examines the evolution and design of interstate water allocation instituti...

France is currently embarking upon a drastic reform of quantitative water resources management. This reform relies on two principles: the definition of an upper limit to water abstraction per water body and the decentralization of the responsibility for allocating water among users, in particular in the agricultural sector. This paper looks at possible institutional arrangements and incentive-b...

the development of market-based task allocation mechanisms is currently being discussed as sustainable, flexible and efficient approaches to water resources management and its redistribution among different users. nevertheless, the market potential for efficient water allocation depends on the specific circumstances of the market and the item being traded i.e., water. experience has demonstrate...
