Abstract

A software radio receiver comprises a broadband low-noise amplification unit used for accessing an input signal to amplify the input signal to form an amplified signal; a fractional mixer used for carrying out frequency conversion on the amplified signal to form a mixed signal; an analog-to-digital converter used for converting the frequency mixing signal into a digital signal; a DSP and softwaredemodulation unit used for processing the digital signal and realizing signal demodulation; and a clock unit used for providing a clock for the shift register and providing a clock for the analog-to-digital converter and the DSP and software demodulation unit. The software radio receiver is used for physically implementing software radio technology.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a software radio receiver. Background technique [0002] Broadcast communication systems are closely related to our daily life, such as mobile phones, TVs, telephones, WiFi and Bluetooth, etc. These communication systems are usually realized by hardware, for example, a mobile phone transceiver is used for mobile phone communication, and a WiFi transceiver is used for wireless local area network communication. A hardware-implemented communication system cannot support multiple communication protocols, nor can it switch between different communication protocols. For example, a mobile phone transceiver cannot directly support WiFi or Bluetooth communication. In contrast to this is a computer. Under the condition that the hardware central processing unit (CPU) remains unchanged, the computer can meet different needs by downloading different software. [0003] So the concept of...
