IET Signal Processing, Volume 17, Issue 6, June 2023., 2023 A dual‐function radar‐communications (DFRC) system based on the circulating code array is presented to address the contradiction between radar and communications system in beam scanning and beam coverage. Processed orthogonal frequency‐division multiplexing (OFDM) signal is transmitted by the circulating code array as the base signal to improve the ...

Continuous unconstrained PSO‐PTS strategy to maximize HPA energy efficiency for FBMC‐OQAM systems
IET Communications, Volume 17, Issue 5, Page 614-631, March 2023., 2023 This paper theorizes the optimal FBMC‐OQAM signal distribution (OFSD), which has a global and steady feature and evaluates the maximal HPA efficiency‐suited multi‐carrier modulation (MCM) signal. The intelligent enhanced PTS algorithm traces the signal distribution for maximal HPA efficiency to keep supply‐side energy‐saving.

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 ...

Capacity analysis of WCC-FBMC/OQAM systems [PDF]
2016 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2016 This paper evaluates the capacity of weighted circularly convolved FBMC/OQAM systems. A rigorous mathematical model is derived to calculate the increase of capacity that can be obtained thanks to the lattice structure of the modulation and the exploitation of the intrinsic interference.
