摘要： 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 a transmitter of a communication system, wherein the transmitter includes a circular convolution module that is configured to circularly convolve a preset number of values with a group of M symbols from a total number of symbols, an M-point DFT module that is configured to process output of the circular convolution to generate a first set of discrete Fourier transform (DFT) samples, and an N-point IDFT module that is configured to process the first set of DFT samples to obtain a first set of inverse discrete Fourier transform (IDFT) samples for onward transmission to a receiver.

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.

摘要： 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).

摘要： 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.
