Multi-Band Time of Arrival Estimation for Long Term Evolution (LTE) Signals

GPP LONG TERM EVOLUTION LTE SCHEDULING Sultan

Future generation cellular networks are expected to deliver an omnipresent broadband access network for an endlessly increasing number of subscribers. Long term Evolution (LTE) represents a significant milestone towards wireless networks known as 4G cellular networks. A key feature of LTE is the implementation of enhanced Radio Resource Management (RRM) mechanism to improve the system performan...

Multi-user Detection Techniques for Potential 3gpp Long Term Evolution (lte) Schemes

This paper is concerned with multi-user detection techniques for orthogonal frequency division multiplexing – interleave division multiple access (OFDM-IDMA) and IDMA with cyclic prefix (IDMACP). These two schemes have attractive features such as low-cost multi-user detection/equalization and flexible rate adaptation. We will show that significant performance improvement (i.e., the so-called mu...

Time delays and angles of arrival estimation using known signals

Channel estimation in a multipath mobile communication system is addressed in this paper, and a novel approach based on the linear prediction in frequency domain and the singular value decomposition technique is presented for joint estimation of the angles of arrival and the time-delays of multiple reflections of a known signal. Simulation results illustrating the performance of the proposed al...

The Evolution of Long-term Care Programs; Comment on “Financing Long-term Care: Lessons From Japan”

The need for long-term care (LTC) represents a “new social risk,” one that overlaps with and complements systems of care that pre-date such programs, complicating LTC program design. This commentary expands on Ikegami’s discussion of how these structural factors must be accommodated, as well as historical and cultural factors that influence public expectations of such a...
