Modulating waveforms for OFDM
Orthogonal frequency division multiplexing (OFDM) is a popular transmission technique that is employed in applications such as Digital Audio Broadcasting, Asymmetric Digital Subscriber Line and wireless LAN. In this work we consider design of modulating waveforms for OFDM in the presence of the delay spread and system impairments such as frequency offset and timing mismatch. We give a complete ...
متن کاملAnalysis of Candidate Waveforms for 5G Cellular Systems
Choice of a suitable waveform is a key factor in the design of 5G physical layer. New waveform/s must be capable of supporting a greater density of users, higher data throughput and should provide more efficient utilization of available spectrum to support 5G vision of “everything everywhere and always connected” with “perception of infinite capacity”. Although orthogonal frequency division mul...
متن کاملModulation Formats and Waveforms for the Physical Layer of 5G Wireless Networks: Who Will be the Heir of OFDM?
5G cellular communications promise to deliver the gigabit experience to mobile users, with a capacity increase of up to three orders of magnitude with respect to current LTE systems. There is widespread agreement that such an ambitious goal will be realized through a combination of innovative techniques involving different network layers. At the physical layer, the OFDM modulation format, along...
متن کاملPerformance Analysis of Ofdm for 5g Mimo System
In this research paper basic concepts of 5G MIMO system is discussed in detail and BER performance of OFDM system for 5G MIMO system is simulated and results are shown on display. A novel technique CMA method to minimize PAPR reduction is proposed so that bit error rate performance can be improve significantly. Number of symbol considered 100, number of transmitter antenna is taken two and numb...
متن کاملImproved N-continuous OFDM for 5G Wireless Communications
N-continuous orthogonal frequency division multiplexing (NC-OFDM) is a promising technique to obtain significant sidelobe suppression for baseband OFDM signals, in future 5G wireless communications. However, the precoder of NC-OFDM usually causes severe interference and high complexity. To reduce the interference and complexity, this paper proposes an improved time-domain N-continuous OFDM (TD-...
