Abstract

The invention discloses a wired and wireless converged communication system, a wired and wireless converged communication method and a method and a device for generating multi-waveband signals. The method for generating the multi-waveband signals in the wired and wireless converged communication system comprises the steps: in a central office, data signals are uploaded through an offset port of a Mach-Zahnder modulator, and clock signals with 10 GHz of frequency is used as drive signals of the Mach-Zahnder modulator to obtain multi-waveband output signals with base bands, primary carrier waves and secondary carrier waves; and in a base station, a base band signal, a microwave signal with 20 GHz of frequency and a millimeter wave signal with 40 GHz of frequency are separated from the multi-waveband output signals through a carrier wave separating device. The generation of the multi-waveband signals is achieved only by using one single-drive modulator, the cost is saved, the adjustment is simple, optimal results are easily obtained, each spectrum component of downstream multi-waveband signals contains data, and accordingly the frequency spectrum utilizing rate is improved.

Description

technical field [0001] The invention relates to a communication system, in particular to a wired and wireless fusion communication system, method, and multi-band signal generation method and device. Background technique [0002] With the development of optical fiber communication and wireless communication, the integration of wireless and wired has become an irreversible trend. Therefore, the next generation access network must be able to provide wired and wireless services at the same time, so that users in such a network can get Greater convenience and more choices. [0003] The wireless and wired communication system needs to realize large capacity, large bandwidth and higher flexibility in an economical way. Among these technologies, multi-band signal transmission is an ideal solution. It can simultaneously transmit baseband signals and multiple wireless signals to provide services for different users, thereby improving system flexibility and reducing system costs. Sin...
