摘要:
Aspects of the present disclosure provide systems and methods for determining placement of telecommunication equipment so as to minimize network cost, maximize network utilization, and meet Service Level Agreements (SLA) for the given network topology and demand requirements. Systems and methods of the present disclosure can be configured to determine minimum number of telecommunication equipment and placement thereof by constructing, based on a given network topology and service requirement, using a heuristic algorithm, an initial population of possible solutions, iterating over the possible solutions to increase optimality of solution based on any or a combination of cost of placement of the one or more telecommunication equipment and number of telecommunication equipment to be placed, and identifying most optimal solution for the placement of the one or more telecommunication equipment.

A method and system has been provided in which the security of passwords in general and offline passwords in particular can be enhanced and which can enable users to be authenticated into secure network systems via network elements (NEs) in case of non-availability of centralized authentication system (CAS). The overall security of network or CAS or systems operating in isolated yet secured environment can be prevented from compromise even if the offline password is compromised. Related apparatus, systems, techniques, and articles are described.

The present disclosure relates to transmission of information across a communication channel efficiently and without error. The present disclosure also enables transmission of information across a communication channel such that the Peak to Average Power Ratio (PAPR) is one (zero in decibels). The present disclosure also enables transmission of information across a communication channel such that the information transmitted is present only along a finite number of orthogonal frequencies. The present disclosure also combines advantages of both Single-carrier Transmission (SCT) and Multi-Carrier Transmission (MCT) systems (e.g. Orthogonal Frequency Division Multiplexing (OFDM) systems).

The present disclosure generally relates to a wireless communication system that provides lower peak to average power ratio (PAPR). In particular, the present disclosure pertains to communication systems and methods for achieving low peak to average power ratio (PAPR) for transmitted symbols of wireless devices. In an aspect, the present disclosure relates to transmitter of a communication system, wherein the transmitter can include a source encoding module that is configured to generate source coded symbols from information to be transmitted by the transmitter, a preset values based multiplication module that is configured to multiply M symbols from the generated source coded symbols with M preset values to generate a first set of multiplied samples, and an N-point IDFT module that is configured to process the first set of multiplied samples to obtain a first set of inverse discrete Fourier transform (IDFT) samples for onward transmission to a receiver.

Systems and methods of the present disclosure enable LTE unaware devices to access Internet by reusing ADSL billing and OSS infrastructure in a LTE deployment by enabling the LTE to provide a transparent Internet pipe through which multiple terminal equipments (TEs) can be connected to a single CPE, and at the same time enabling each user to be billed separately using the existing broadband remote access servers (BRAS).

Aspects of the present disclosure aim at providing three orthogonal waveforms that can be used for transmitting 3n bits (n bits from each waveform) at a given frequency. Such three orthogonal waveforms can be used in applications such as QAM to create a 3-dimensional QAM, along with use in other like applications such as in Orthogonal frequency-division multiplexing (OFDM), Quadrature Phase Shift Keying (QPSK), Binary Phase Shift Keying (BPSK), among others. In an aspect, a method of the present disclosure includes a step of generating three orthogonal waveforms as cos(θ)+k, cos(θ+2π/3)+k, and cos(θ+4π/3)+k, where k is the DC component and can have a value of 0.5 volts, and θ=2πft with f being the (baseband or passband) frequency=1/T, with T being Time Period, and t being time. Cosine waveforms can be equivalently replaced by sine waveform separated by 120 degrees.

The embodiments herein provide a method and system for extending battery power at cell sites. The method for extending battery power at cell sites comprises providing a combination of a valve-regulated lead-acid (VRLA) battery and a Li-ION battery, mixing cell chemistry of the VRLA battery and the Li-ION battery and charging the VRLA-Li-ION battery combination with a single charger circuit. The method further comprises providing a rectifier to both the VRLA battery and the Li-ION battery and activating each battery based on the available power. The Li-ION battery and the VRLA battery are the primary battery and secondary battery. The charging current through the VRLA battery is regulated by varying a pulse width of a high current switch based on the current read through the current sensor attached to a VRLA current path.
