摘要
研究基于无线传输的CBTC系统车-地通信抗干扰技术,通过分析无线局域网中的同频干扰,结合重复累积码、感知无线电、一致性测试3项技术,提出1套在CBTC系统设计和系统运营两个阶段抑制同频干扰的完整解决方案。
Combined with the technology of repeat-accumulate codes, cognitive radio and conformance testing, the whole solution for restraining co-channel interference in the two stages of CBTC system design and system operation is presented by analyzing the same frequency interference problem of WLAN.
