Performance of SC-FDMA with transmit power allocation and Frequency-Domain Equalization

Variable packet splitting transmission in multi-relay cooperative communications with DF and DAF for SC-FDMA

“…The waterfilling power allocation (WF/PA) method has been proposed to improve the system performance [24][25][26][27]. The WF/PA method mitigates the deep faded channel by using the optimum power assignment.…”

“…Therefore, in this article, we propose the optimum packet splitting in the multi-relay cooperative communication systems. Cooperative communications can improve the system performance by using the power allocation (PA) [24][25][26][27][28]. This method is also effective in the multi-relay cooperative communications [26].…”

“…Therefore, [27] has adopt the waterfilling power allocation (WF/PA) method. The WF/PA method mitigates the deep faded channel by using the optimum power [24][25][26][27]. However, the PA method requires large feedback information (FBI) since it has to feedback the channel state information (CSI) of each sampling point in a frequency domain.…”

Peak power reduction techniques for multi-channel SC-OFDM

“…In addition, computationally efficient frequency domain equalizers (FDE) can be utilized to combat multipath fading channels [3,4]. Furthermore, it has been shown that Nyquist filtered SC-OFDM signals can capture the frequency diversity gains in multipath fading channels [5].…”
