Improved Nyquist-I Pulses to Enhance the Performance of OFDM-Based Systems
(Springer, 2017)
Pulse shaping is used in orthogonal frequency division multiplexing (OFDM) based systems to reduce inter-carrier interference (ICI) power and peak-to-average power ratio (PAPR), which are considered the major weaknesses ...
Suppressing the effect of ICI power using dual sinc pulses in OFDM-based systems
(Elsevier, 2016)
Sensitivity to frequency offset in orthogonal frequency division multiplexing (OFDM)-based systems allow unwanted interference among the subcarriers, which results in intercarrier interference (ICI). A novel family of ...
ICI Reduction in OFDM Systems Using a New Family of Nyquist-I Pulses
(IEEE, 2015)
In this paper the parametric linear combination pulse (IPLCP) is proposed. The IPLCP is a new family of Nyquist-I pulses with two additional degrees of freedom to minimize the inter-carrier interference (ICI) power in ...
A digital-analogue match filter for piecewise square pulses
(Instituto Geofísico del Perú, 1977-02-03)
It is well known that the optimum signal to noise ratio in a radar is obtained when the receiver response is matched to the transmitter pulse shape. A matched receiver has an impulse response, g(t), equal to the negative ...
Subsiding OOB Emission and ICI Power Using iPOWER Pulse in OFDM Systems
(Univ Suceava, Fac Electrical Eng, 2016)
A novel family of Nyquist-I pulses called iPOWER is proposed with a new design parameter. that provides an extra degree of freedom for a certain roll-off factor, a. The proposed pulse is examined and compared with other ...
Beating spatio-temporal coupling: Implications for pulse shaping and coherent control experiments
(Optical Society of America, 2011-12)
Diffraction of finite sized laser beams imposes a limit on the control that can be exerted over ultrafast pulses. This limit manifests as spatio-temporal coupling induced in standard implementations of pulse shaping schemes. ...
