AI Technical Summary

Technical Problem

Existing StarFlash mice suffer from problems in power consumption control, such as inefficient coding schemes, crude power management, and insufficient system coordination. This results in limited power consumption compression space in high-frequency micro-movement or continuous clicking scenarios, and excessive wake-up and synchronization overhead, which affects user experience.

Method used

A hierarchical architecture based on Polar code and SLE co-optimization is adopted. Through the Polar code encoding module, SLE control engine and cross-layer optimization interface, dynamic configurable CRC-assisted SCL decoding, Kalman filter prediction of mouse movement speed, dynamic binding of coding block length and sleep cycle, nonlinear mapping from signal-to-noise ratio to coding rate and low-latency wake-up channel are realized to form a closed-loop control system.

Benefits of technology

It achieves an overall power consumption reduction of 42.7%, maintains an ultra-low bit error rate on the order of 10⁻⁵ and a transmission latency of less than 0.5ms in a complex interference environment at 2.4GHz, triples the battery life, reduces the logic area by 35%, reduces the cost by 12%, and supports rapid adaptation to different hardware platforms.

Abstract

The invention belongs to the field of star flash mouse communication, and discloses a star flash mouse low-power-consumption communication system and method based on Polar code and SLE collaborative optimization, the system adopts a layered architecture design, collaborative optimization of energy efficiency and performance is realized through deep coupling of a physical layer and a link layer, and the performance of the system is improved. The core of the system is composed of three functional units including a Polar code coding module, an SLE control engine and a cross-layer optimization interface, and a complete closed-loop control system is formed. According to the invention, through deep cooperation of the Polar code and the SLE mechanism, the overall power consumption is reduced by 42.7% compared with the traditional scheme; according to the Polar code dynamic construction method based on track prediction, an ultra-low bit error rate of 10 <-5 > magnitude can still be kept in a 2.4 GHz complex interference environment, and in combination with signal-to-noise ratio self-adaptive coding parameter adjustment, it is ensured that transmission delay within 0.5 ms is always kept from a low-speed office scene to a high-speed electronic sports scene; in the aspect of engineering implementation, the method has the capability of quickly adapting to hardware platforms of different manufacturers, and a complete solution with high performance and low cost is provided for large-scale commercial use of the satellite flash technology in the consumer electronics field.
