Adaptive Two-Stage Detection Scheme in Synchronous Two-User CDMA Systems by Yong Jiang A conventional single user detector is not optimum in the multiuser environment because the multiuser interference can not be modeled as an additive Gaussian process. Such a receiver is very vulnerable to the near-far situation. The receiver that is optimum for multiuser environment has high complexity and re...
متن کامل6 Green and Efficient RAN Architectures
The explosive increase of capacity demand has resulted in more dense deployments involving a growing number of BSs. To make future mobile networks sustainable from an economic viewpoint, they should provide more while simultaneously cost less. Installing smaller cells in areas where infrastructure can provide the required backhaul connectivity is the current natural evolution of radio access ne...
متن کاملUser Assignment in C-RAN Systems: Algorithms and Bounds
In this work, we investigate the problem of mitigating interference between so called antenna domains of a cloud radio access network (C-RAN). In contrast to previous work, we turn to an approach utilizing primarily the optimal assignment of users to central processors in a C-RAN deployment. We formulate this user assignment problem as an integer optimization problem, and propose an iterative a...
متن کاملA Novel Two-Stage Mathematical Model for Green Supplier Development
Nowadays, numerous processes of any supply chain are done by suppliers and consequently they cause a massive amount of pollution released to the nature. Hence, greening the suppliers has become a necessity. Although most of green supplier development programs need high investment, formal optimization models that address this issue are very rare. This paper mainly aims to address this prob...
متن کاملA green protocol for synthesis of pyran annulated hetrocyclic systems using Na2SO4 as an efficient catalyst
Na2SO4 as an inexpensive and effective catalyst has provided a green protocol for the synthesis of tetrahydrobenzo[b]pyran, pyrano[2,3-d]pyrimidinone and dihydropyrano[3,2c]chromene derivatives from the three-component domino reaction of aromatic aldehydes and malononitrile with 4-hydroxycoumarin/ dimedone/ barbituric acid in ethanol/water as a mixture of solvent that, this mixture entirely is ...
