Spectral Efficiency Sample Clauses

Spectral Efficiency. ‌ The physical path design of the Ethernet twisted-pair copper media standard 10GBASE-T (802.3an) represents one of the most advanced constellations in common use at very high symbol rates. As shown below in Figure 22, each of the four channels uses an 800 Mbaud symbol rate with 3.125 bits per DSQ-128 dimension, giving 2.5 Gb/s/copper pair. This is derived using 16-XXX at 4 bit/dim, which is reduced to 3.125 bit/dim by 2-D alphabet partitioning and coding. The cable transmission matrix is high cross-linked, suggesting that MIMO-OFDM could be used. However, latency issues make this a poor choice; a factor often overlooked in the use of OFDM signaling. The use of intrinsic echo and cross-talk cancellation offers a strong (and essential) advantage in signal-to-noise ratio (SNR). Overall a BER of 10-12 is achieved with a SNR of 23.32 dB. A low-density, parity check code (LDPC [2048,1723]) offers 8 dB coding gain. Figure 22: DSQ-128 Modulation. For microwave mobile backhaul, over the last ten years, state of the art spectral efficiency has increased from a modest 1.2 b/s/Hz to a record value of 35 b/s/Hz demonstrated by Ericsson at the Mobile World Congress 2011 in Barcelona. Enabling technologies for such an increase in spectral efficiency are MIMO technologies such as polarization multiplexing and spatial multiplexing, and high order modulation where 512QAM is commercially available and 1024QAM and higher are to be introduced to the market [31]. Recent records in spectral efficiencies achieved in optical communications e.g. over multi-mode fibres, rely all on off-line processing after sampling the signals in a high-speed oscilloscope.

  • Energy Efficiency The contractor shall comply with all mandatory standards and policies relating to energy efficiency which are contained in the energy conservation plan issued in compliance with the Energy Policy and Conservation Act (Pub.L. 94-163) for the State in which the work under this contract is performed.

  • PRODUCTIVITY The Union shall place no limitations upon the amount of work which an Employee shall perform during the working day and there shall be no restrictions imposed against the use of any type of machinery, tools or labour saving devices.

  • Maintenance of Profitability Seller shall not permit, for any Test Period, Net Income for such Test Period, before income taxes for such Test Period and distributions made during such Test Period, to be less than $1.00.

  • Quality All products will be new and unused. All products provided by the Contractor must meet all federal, state, and local standards for quality and safety requirements. Products not meeting the requirements of this section will be deemed unacceptable and returned to the Contractor for credit at no charge to the State.

  • Reliability Reliability targets (Mean Time Between Failures (MTBF)) are defined in the technical specifications as set out in the Contract. Notwithstanding any possible application of penalties relating to reliability defined in the Contract, Goods shall remain covered by the warranty defined in this Article 16 as long as the reliability commitments have not been reached.

  • Profitability The Board reviewed detailed information regarding revenues received by XXXX under the Agreement. The Board considered the estimated costs to XXXX, and pre-tax profits realized by XXXX, from advising the DWS Funds, as well as estimates of the pre-tax profits attributable to managing the Fund in particular. The Board also received information regarding the estimated enterprise-wide profitability of DIMA and its affiliates with respect to all fund services in totality and by fund. The Board and the Fee Consultant reviewed XXXX’s methodology in allocating its costs to the management of the Fund. Based on the information provided, the Board concluded that the pre-tax profits realized by XXXX in connection with the management of the Fund were not unreasonable. The Board also reviewed certain publicly available information regarding the profitability of certain similar investment management firms. The Board noted that, while information regarding the profitability of such firms is limited (and in some cases is not necessarily prepared on a comparable basis), DIMA and its affiliates’ overall profitability with respect to the DWS Funds (after taking into account distribution and other services provided to the funds by XXXX and its affiliates) was lower than the overall profitability levels of most comparable firms for which such data was available. Economies of Scale. The Board considered whether there are economies of scale with respect to the management of the Fund and whether the Fund benefits from any economies of scale. The Board noted that the Fund’s investment management fee schedule includes fee breakpoints. The Board concluded that the Fund’s fee schedule represents an appropriate sharing between the Fund and DIMA of such economies of scale as may exist in the management of the Fund at current asset levels.

  • Dependability a) Requires constant supervision to perform daily routine correctly b) Occasionally misses necessary task c) Rarely misses necessary task and is reliable d) Outstanding reliability and job is always completed correctly

  • Monitoring System In each case in which the Custodian has exercised delegated authority to place Assets with a Foreign Custodian, the Custodian shall establish a system, to re-assess or re-evaluate selected Foreign Custodians, at least annually in accordance with Rule 17f-5(c)(3).

  • Staffing There shall be a clinician employed by the outside contractor for EAP Services who will be on-site a minimum of 20 hours a week. The clinician shall report directly to the outside contractor, Peer Assistance Oversight Committee and the MIF liaison.
