摘要
讨论了基于微波传输的IP化回传网络(MBH)在现行的CES包处理方式下可能导致的支路误码率劣化问题,分析了其产生原因并提出了两点改进措施。推导了改进后的支路误码率计算公式,验证了这些措施对支路误码率劣化的有效性。这种改善将有助于IP化的MBH网络能可靠地实现微波传输。
IP-based mobile backhauling network of LTE is a up-to-date technology.This paper discusses the tributary BER degradation.This degradation was potentially caused by current process mode of CES packets in IP-based MBH based on microwave transmission.The cause of the degradation is analyzed and two solutions are also proposed subsequently.Relevant calculation formulas of improved tributary BER are deduced.And the improvement of tributary BER degradation is verified after adoption of these solutions.It will contribute to reliable microwave transmission of IP-based MBH.
