Abstract

The invention relates to the field of radio communication, and discloses a software radio communication method and system. The method comprises the following steps: receiving a radio frequency signal, selecting a local oscillator according to a wave band on which the radio frequency signal is positioned, and shifting the wave band on which the radio frequency signal is positioned to a fixed intermediate frequency; digitally converting a broadband intermediate frequency signal, shifting the digitally-converted broadband intermediate frequency signal to a zero intermediate frequency via down conversion, and performing multi-rate conversion to obtain a low-speed baseband signal; and calling a preset mode in a software way, demodulating the low-speed baseband signal and completing information recovery of the demodulated signal to obtain receiving information. Through the technical scheme of the invention, multi-band, multi-rate and multi-mode signal modulation and demodulation can be realized, and a real software radio system becomes a reality. The method and system have very high flexibility, openness and expandability, and can be widely applied to the field of radio communication.

Description

Technical field [0001] The invention relates to the field of wireless communication, in particular to a software radio communication method and system. Background technique [0002] In recent years, with the development of mobile communication technology, devices or service parties that developed independently in the early days often used different ways to achieve communication, which led to the coexistence of multiple digital wireless communication standards. Although various communication systems may have basically similar basic structures in terms of hardware structure, their respective signals are substantially different. For example, frequency bands, modulation methods, encoding methods, encryption modes, etc., will have different implementation methods, resulting in actual equipment. The details are significantly different. [0003] Since each signal system has different requirements for its communication equipment, the equipment between different systems is not compatible a...
