Multi-Band Triangular Frequency Modulation Signal Generation Based on Gain-Switched Laser
Optics Communications, 2023A multi-band triangular frequency modulation signal generation method is proposed and verified by simulation. This is a simple photonics method based on distributed feedback gain switching states of semiconductor lasers without the need for complex external modulators. The carrier frequency and bandwidth of the generated triangular frequency modulation

Design of a multi-band FMCW radar module
2013 10th Workshop on Positioning, Navigation and Communication (WPNC), 2013This paper presents a multi-band frequency-modulated continuous wave (FMCW) radar module. The module can perform ranging in a wide frequency range, including the 2.4GHz and 5.8GHz ISM bands. It incorporates an application specific integrated circuit (ASIC) for processing the analogue signals and a field programmable gate array (FPGA) as digital signal ...

Performance Evaluation of Adaptive Modulation for Multi-Band OFDM
IEICE Transactions on Communications, 2006In this letter, we provide a performance evaluation of a Multi-Band Orthogonal Frequency Division Multiplexing (MB-OFDM) with adaptive modulation in a multipath fading channel. The MB-OFDM system in conjunction with adaptive modulation technique can be considered as one of the solutions for severely degraded channels such as those common in frequency ...

LTCC Front-end Modules for Multi-band Applications
2006 European Microwave Conference, 2006This paper presents LTCC front-end modules for multi-band applications. A dual-band module composed of a diplexer, a CDMA SAW duplexer, and a GPS SAW filter for CDMA/GPS applications and a tri-band module employing PIN diodes for CDMA/GPS/PCS applications are implemented based on LTCC substrates.

IEEE Transactions on Circuits and Systems I: Regular Papers, 2020
This paper presents a reconfigurable delta-sigma modulation (DSM) architecture for concurrent multi-band transmission. The reconfigurability in terms of carrier spacing and the number of simultaneous carrier transmission is useful for applications such as carrier aggregation in 5G. This paper uses $4^{th}$ order reconfigurable multi-band DSM (RMB-

Experimental Verification of Visible Light Communications based on Multi-Band CAP Modulation
Optical Fiber Communication Conference, 2015© 2015 OSA.A multi-band CAP system is experimentally demonstrated for the first time in VLC. We show that with an 8-CAP testbed spectral efficiencies (∼4.75 b/s/Hz) at a realistic distance of 1 m can be reached.

Multi-band SIW antenna with modulated metasurface at 5G frequency
2018 IEEE Indian Conference on Antennas and Propogation (InCAP), 2018This paper proposes a multi-band SIW antenna which is linearly polarized. The antenna consists of a T-shaped radiator inscribed on the upper side of the dielectric substrate. This radiator is responsible for multi-band occurrence. The operating frequency is chosen to be 28 GHz, which is a valid selection for 5G applications.
