Analog/digital conversion data transmission method, transmitting device and analog/digital conversion chip

Abstract

The invention is applied to the field of communication and provides an analog / digital conversion data transmission method, an analog / digital conversion data transmission transmitting device and an analog / digital conversion chip. The analog / digital conversion data transmission method comprises the following steps of: carrying out frequency shift on multiple groups of simulation data to generate a plurality of groups of digital data which are independently distributed within a first preset bandwidth; filtering the digital data to filter out out-of-band information; and distributing the filtered digital data within a second preset bandwidth in a non-overlapped way. According to the analog / digital conversion data transmission method disclosed by the invention, the frequency shift on data contents is realized by using a plurality of analog / digital conversion cores inside the analog / digital conversion device to filter out unnecessary out-of-band information; effective information of the analog / digital conversion cores is redistributed by fully utilizing the transmission bandwidth of an interface and is efficiently transmitted to next-stage equipment for processing, so that the data transmission pressure between the converter and an FPGA (Field Programmable Gate Array) or ASIC (Application Specific Integrated Circuit) is greatly reduced and the design complexity of the multi-frequency-band receiver is effectively simplified.

Description

technical field [0001] The invention belongs to the communication field, and in particular relates to an analog-to-digital conversion data transmission method, an analog-to-digital conversion data transmitter and an analog-to-digital conversion chip. Background technique [0002] At present, in the existing wireless communication base station technology, it is necessary to convert the received analog signal into a digital signal, and then perform calculation processing in the digital domain to complete various functions and achieve the purpose of information transmission. The analog digital converter (Analog Digital Converter, ADC) is to discretize the analog signal in terms of time and amplitude, and convert it into a digital signal. This type of device is the most common device used in the existing analog-digital hybrid system. [0003] The existing ADC architectures are relatively common digital interface methods for parallel output of ADCs. Most of them adopt two methods...
