Description

Technical Field

[0001] This utility model belongs to the field of domestic embedded wireless short-range communication technology, specifically relating to a wireless short-range communication circuit based on star flash technology. Background Technology

[0002] Traditional short-range wireless communication technologies such as WiFi and Bluetooth have many limitations when facing emerging scenarios. For example, Bluetooth performs poorly in terms of speed and latency, making it difficult to meet the high real-time and reliability requirements of smart cars, such as the short-range communication needs of vehicle active safety systems. While WiFi offers high transmission speeds, it suffers from asynchronous operation and system efficiency issues, and its relatively high power consumption limits its application in power-sensitive smart terminals and smart home devices.

[0003] With the rapid development of intelligent vehicles, intelligent terminals, smart homes, and intelligent manufacturing, higher demands are being placed on wireless short-range communication technologies in terms of low latency, high reliability, precise synchronization, high speed, high concurrency, high information security, and low power consumption. For example, autonomous driving systems in intelligent vehicles require high-speed, low-latency, and highly reliable communication between sensors and controllers to ensure safe vehicle operation; multiple devices in smart homes need to achieve synchronized control and stable connectivity to provide a good user experience.

[0004] StarScan is a new generation of short-range wireless communication technology native to China, drawing on the concepts and achievements of advanced communication technologies such as 5G. For example, it employs asynchronous HARQ (Hybrid Automatic Repeat Request) technology, frequency domain scheduling design, and frame structure similar to 5G. These technologies enable StarScan to achieve high-speed, low-latency, and high-reliability communication in short-range scenarios. Simultaneously, StarScan integrates advanced signal processing algorithms and encoding / decoding techniques, such as Polar data channel coding, improving signal anti-interference capabilities and transmission reliability. Furthermore, its emergence helps enhance China's voice and influence in the global communications field, promoting Chinese technical standards onto the world stage. Utility Model Content
