Abstract

Millimeter wave (mm-wave) communication holds great promise as a wireless communication method for the future due to its substantial advantages in terms of bandwidth and capacity. As communication capacity continues to increase, the ability to resist interference through frequency-hopping (FH) becomes essential for future applications. The FH bandwidth and rate are key technical specifications in FH transmission system. In this paper, the method of fast and large-range FH mm-wave signal generation based on the optical heterodyne technology is investigated to improve the technical specifications of FH bandwidth and rate, including using optical switch based wavelength selection, and direct modulated laser (DML) chirp effect. The hybrid method of optical switch and DML is proposed, and a real-time system demonstration with the data rate that supporting 10-Gigabit optical module, FH bandwidth of up to 10 GHz, FH rate of 10 kHz, and wireless distance of 1.1 m is achieved, proving the feasibility of a large-scale high-speed millimeter wave frequency hopping transmission system.

期刊介绍： Innovations in optical fiber technology are revolutionizing world communications. Newly developed fiber amplifiers allow for direct transmission of high-speed signals over transcontinental distances without the need for electronic regeneration. Optical fibers find new applications in data processing. The impact of fiber materials, devices, and systems on communications in the coming decades will create an abundance of primary literature and the need for up-to-date reviews. Optical Fiber Technology: Materials, Devices, and Systems is a new cutting-edge journal designed to fill a need in this rapidly evolving field for speedy publication of regular length papers. Both theoretical and experimental papers on fiber materials, devices, and system performance evaluation and measurements are eligible, with emphasis on practical applications.
