Joint radar communication system design based on filter bank multicarrier modulation scheme
IET Radar, Sonar &Navigation, Volume 17, Issue 1, Page 47-62, January 2023., 2023 Abstract Since orthogonal frequency division multiplexing (OFDM) signals are sensitive to Doppler shift, OFDM signals with cyclic prefix (CP) not only reduce the communication rate but also result in symmetric pseudo peaks in the ambiguity function of the radar, which eventually lead to the degradation of the performance of the joint radar ...

Journal of Electrical and Computer Engineering, Volume 2023, Issue 1, 2023., 2023 Nowadays, multicarrier modulation schemes are being widely used in wireless communication system than single‐carrier modulation techniques. Single‐carrier modulation schemes are less capable of dealing with multipath fading channels than multicarrier modulation schemes, which results in lower spectral efficiency.

PAPR reduction technique for FBMC based visible light communication systems
IET Communications, Volume 16, Issue 15, Page 1807-1814, September 2022., 2022 Abstract One of the critical challenges in multicarrier‐based systems is peak to average power ratio (PAPR). Recently, Filter Bank Multicarrier (FBMC) is proved to be a promising candidate that can replace the traditional orthogonal multiplexing division (OFDM) scheme due to its better spectral efficiency, reducing both inter‐channel interference (ICI)

Effective signal to intrinsic interference plus noise ratio analysis of affine precoded FBMC system
Electronics Letters, Volume 58, Issue 9, Page 375-378, April 2022., 2022 Abstract An affine precoding and decoding (APD) method of channel estimation and data detection in the filter bank multi‐carrier (FBMC) system is implemented, and it is found to be useful from bit error rate (BER) perspective. Effective average signal to intrinsic interference plus noise ratio (SINReff)$(\text{SINR}_{\text{eff}})$ is derived ...

IET Communications, Volume 16, Issue 2, Page 142-150, January 2022., 2022 Abstract Partial transmit sequence (PTS) is an effective method to reduce the peak‐to‐average power ratio (PAPR) of orthogonal frequency division multiplexing (OFDM) system, but it is not suitable for the filter bank multi‐carrier with offset quadrature amplitude modulation (FBMC/OQAM) system because of the overlapping structure of FBMC/OQAM signals ...

Channel Measurement and Noise Estimation in FBMC/OQAM‐Based IoT Networks
Wireless Communications and Mobile Computing, Volume 2022, Issue 1, 2022., 2022 Channel measurement plays an important role in the emerging 5G‐enabled Internet of Things (IoT) networks, which reflects the channel quality and link reliability. In this paper, we address the channel measurement for link reliability evaluation in filter‐bank multicarrier with offset quadrature amplitude modulation‐ (FBMC/OQAM‐) based IoT network ...

Interference-free SDMA for FBMC-OQAM [PDF]
EURASIP Journal on Advances in Signal Processing, 2013 Filter-bank multi-carrier (FBMC) modulations have recently been considered for the emerging wireless communication systems as a means to improve the utilization of the physical resources and the robustness to channel time variations. FBMC divides the overall frequency channel in a set of subchannels of bandwidth proportionally decreasing with the ...

Conjugate-Root Offset-QAM for Orthogonal Multicarrier Transmission [PDF]
, 2015 Current implementations of OFDM/OQAM are restricted to band-limited symmetric filters. To circumvent this, non-symmetric conjugate root (CR) filters are proposed for OQAM modulation.
