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 aim at providing three pseudo-orthogonal waveforms that can be used for transmitting 3n bits (n bits over each waveform) at a given frequency. Use of such three pseudo-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. The three pseudo-orthogonal waveforms can in general be used in any application where complex number algebra is used, and can help increase transmission capacity by additional 50%.

摘要： A method for protection of data traffic transmitted over 2-fiber shared protection ring on STM-1/OC-3 interface is provided. Also, the method involves carrying extra traffic in a ring topology for STM-1/OC-3 interface. This is achieved by fixing the granularity to one of ‘VC12/VC11/VC3/VC12-VC3/VC11-VC3’ for the STM-1 interface and to one of ‘VT2/VT1.5/STS-1’ for the OC-3 interface upfront when the protection is configured on the network element.

摘要： A method for Independent resource request for initial NAS signaling in a communication network comprising of transporting service request message of both the UE and RN via Base station to management entity of Evolved Packet Edge (EPE) within Evolved Packet Core (EPC), as a signaling message over uplink channel referred to as “Independent Resource Request” (IR Request) message. The service request response message from one of the management entity of EPE or management entities of UE and RN within EPC are transported as a signaling message to EPE via Base station over the downlink channel referred to as “Independent Admission Response” (IA Response). This manages bearer setup signaling as a single loop, by transportation of “IR Request” signaling message over uplink and receiving “IA Response” signaling message over downlink channels.

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).
