The distributed base station is mainly composed of base-band unit BBU and radio frequency remote unit RRU. LRRU is a serialized RF remote unit product, which is responsible for providing wireless coverage of the network. It completes UE access and wireless link transmission functions through the Uu interface, provides wireless transmission link, reports measurement information, and transmits system information broadcast. It is connected to the BBU through optical fiber and uses the CPRI interfac

A wireless signal processing platform processes wireless signals for reception, demodulation, decoding, and transmission. Here's how it works: -- Signal Reception: Antennas pick up wireless signals, tailored to specific frequencies and polarizations -- Analog to Digital Conversion: An ADC samples and quantizes the analog signal for digital processing -- Digital Signal Processing: Algorithms like filtering, demodulation, decoding, and equalization are used to enhance and extract information
