Parameter control-based multimode base band processing realizing method

Abstract

The invention discloses a parameter control-based multimode base band processing realizing method which comprises the steps of: constructing a modularized and standardized hardware unit; 2, sampling in an intermediate frequency; 3, downloading an external parameter to increase a frame header and a frame footer, converting data into a frame and inputting to a coding module; 4, enabling the generated modulation signal to enter a switch handover unit, selecting a proper switch for connection; 5, digitizing the whole frequency band by using a broadband ADC (Analog To Digital Converter), completing the intermediate frequency processing by using software, filtering out a narrow band signal and conveying the narrow band signal to a base band; and 6, processing the base band. According to the parameter control-based multimode base band processing realizing method, the communication can be carried out under different protocols, different software modules can be realized by a DSP (Digital Signal Processor) through only calling different controllable parameters without calling the whole software module by adopting a parameter control-based software radio system, the base band processing module is completed, different filter module modulation and demodulation modes, message source coding and decoding and the like are realized, thus operand of the DSP is reduced.

Description

technical field [0001] The invention relates to the technical field of communication electronics, in particular to a method for realizing multi-mode baseband processing based on parameter control. Background technique [0002] The multi-mode wireless communication terminal of the short-range communication system can receive multiple communication services on one terminal device. In order to receive different communication services, it is necessary to install many communication terminal devices to receive different communication services to meet its real-time, accuracy and High transfer rate requirements. In short-range communication, it is to integrate different communication protocols into one device, so that terminal devices can communicate between vehicles and roads under different protocol standards (that is, arbitrarily changing channel access methods, modulation methods, frequencies, etc.) Inter-communication to accommodate different standards. [0003] At present, a...
