Broadband radio intermediate-frequency analogue/digital mixed signal processor

Abstract

The invention discloses a broadband radio intermediate-frequency analogue / digital mixed signal processor, which comprises a broadband intermediate-frequency analogue front end connected with radio frequency equipment, an analogue / digital mixed signal processor connected with the broadband intermediate-frequency analogue front end, an external connection interface connected with the analogue / digital mixed signal processor and a clock allocation system, wherein the broadband intermediate-frequency analogue front end comprises a transmission channel, a receiving channel and an intermediate-frequency local oscillator; the analogue / digital mixed signal processor comprises an ADC, a DAC and a digital signal processing unit; a signal received by the radio frequency equipment is transmitted to the ADC through the receiving channel for analogue / digital conversion and then is transmitted to the digital signal processing unit for processing; and the signal which is processed by the digital signal processing unit and needs transmitting is subjected to digital / analogue conversion and then is transmitted to the radio frequency signal through the transmission channel for transmission. The broadband radio intermediate-frequency analogue / digital mixed signal processor has the characteristics of small volume, low power consumption, wide application range, reliable working performance and good signal processing effect, and can effectively overcome a plurality of defects and shortcomings existing in the conventional like products in China and other countries.

Description

Technical field [0001] The invention belongs to the technical field of wireless mobile communication signal processing, and in particular relates to a broadband radio intermediate frequency analog / digital mixed signal processor. Background technique [0002] With the development of information technology, radio technology has been widely used, and software radio technology has enabled radio signal processing to enter the stage of digital signal processing. Judging from the current domestic and foreign markets, there is a lack of a small, low-power, general-purpose radio intermediate frequency analog / digital mixed signal processing hardware platform that can be superimposed and expanded. Existing foreign products are expensive (for example, Sundance in the UK), and most of them use high-cost technical solutions for direct digitization of intermediate frequency; while most domestic products are signal processing equipment specially designed for a certain application field, so they ...
