Integrated baseband refers to the technology of integrating baseband processing functions in a communication system into a single chip. Baseband processing refers to the process of digital signal processing such as modulation, demodulation, encoding, decoding, error detection and correction of communication signals. Traditionally, baseband processing is usually implemented by multiple independent modules or devices, including modems, codecs, signal processors, and so on. Integrated baseband technology provides higher integration, smaller size, and lower power consumption by integrating these functions into a single chip.
Integrated baseband chip generally includes digital signal processor (DSP), analog front-end interface, modem, codec, error control and other functions. It can receive the analog signal from the RF front end and enter the digital signal processor for processing after analog-to-digital conversion. The operation of modulation and demodulation, codec and other baseband processing algorithms in the digital signal processor. Then, the processed digital signal is converted into an analog signal and output to the RF front end or other external devices through the analog front end interface.
Integrated baseband technology has been widely used in the field of wireless communication, such as mobile communication, wireless LAN, Bluetooth, satellite communication and so on. By integrating baseband chips, communication devices with higher performance, lower power consumption and smaller size can be achieved, improving the overall performance and functions of wireless communication systems.
Integrated baseband is an important concept in the field of mobile communications, which refers to the technology of integrating digital signal processing and radio frequency (RF) modules in the same chip.
It can integrate various components in the transmission module of a mobile phone or other wireless device, such as demodulators, modulators, demodulators, etc., into a small chip, which greatly simplifies the volume and power consumption of the device. The application of integrated baseband technology makes the mobile equipment more compact and efficient, improves the data transmission rate and system performance, reduces the production cost, and promotes the development of mobile communication technology.
