Embodiment Construction

[0026] The multi-domain collaborative multi-mode compatible wireless communication method proposed by the present invention has a flow chart as shown in figure 1 shown, including the following steps:

[0027] (1) Establish a mapping table between a communication frequency band and a communication mode;

[0028] (2) Set the working state of the antenna of the receiving end of the wireless communication as full-band polling, open judgment, and release buffer;

[0029] (3) The above-mentioned receiver antenna searches for a signal at the frequency band f, and performs power detection on the signal to obtain the average power in the frequency band f;

[0030] (4) Set an average power threshold, compare the average power in the frequency band f obtained by the above detection with the average power threshold, if the detected power is greater than the set threshold, then enter step (5), if the detected power is less than the set threshold , return to step (2);

[0031] (5) Accor...

Abstract

The present invention relates to multi-domain collaborative multi-mode compatible wireless communication method that belongs to wireless communication technical field. Three modules of radio frequency, intermediate frequency and baseband accomplish recognition and switch of communication mode on a software radio platform. After the antenna receives signals, then processes by the radio frequency, the intermediate frequency and the baseband in sequence and displays at last. The radio frequency, intermediate frequency and baseband detects signals of their processing domain respectively and the detecting results being sent to control and judgment module, and sends configuration information to the radio frequency, intermediate frequency and baseband simultaneity. The intermediate frequency module and baseband module load corresponding waveform from the waveform elements library according to configured information for accomplishing mode switch. The invention is provided with advantages of three modules accomplish the detection process collaboratively and switch of the mode achieves the objective of accurate detection and intelligent switch via automatic reload.

Description

technical field [0001] The invention relates to a wireless communication method with multi-domain coordination and multi-mode compatibility, in particular to a wireless communication method with multi-domain coordination and multi-mode compatibility for a radio frequency module, an intermediate frequency module and a baseband module, and belongs to the technical field of wireless communication. Background technique [0002] In wireless communication, the coexistence of various standards will exist within a certain period of time. At present, most of the terminals used in the industry can only adapt to one communication standard. The mechanism of the existing dual-mode or multi-mode terminals is through the binding of specific functional hardware. It is done manually, and cannot be identified and switched independently according to the actual communication environment. [0003] SDR technology is an ideal technology to realize multi-mode communication. Through a unified hardw...
