AI Technical Summary
Traditional PIM transmission systems suffer from insufficient pre-allocation of channel resources and the risk of interference pollution in multi-node concurrent scenarios, resulting in insufficient system flexibility and low transmission efficiency. Existing anti-interference algorithms are highly complex and computationally expensive.
By adopting a chain-cascaded fragmentation splicing method, and through group check coding and dynamic fragmentation information table management, combined with forward sliding window pulse search technology, multi-node concurrent PIM transmission without pre-allocation of channel resources is achieved. The hierarchical check mechanism is used to reduce the bit error rate and improve the system robustness.
It improves the system's flexibility and transmission efficiency, reduces computational complexity, and ensures data integrity and reliability in dynamic networking and complex interference environments.
