FPGA-BASED SELF-ADAPTION METHOD AND APPARATUS FOR REMOTE RADIO UNIT (RRU) INTERFACE PROTOCOL

摘要

The present invention provides a kind of method and devices adaptive based on FPGA Base Band Unit equipment RRU interface protocols, and the FPGA includes type register, which comprises RRU loading on-site programmable gate array FPGAs; The FPGA includes one or more interface protocol types; The RRU uses any interface protocol type remote RF unit access BBU; The RRU detects the current interface protocol type of the BBU; The RRU records corresponding type identification for the current interface protocol type in the type register; The RRU is configured for the corresponding interface protocol type of the type identification. The present invention guarantees the unification with opposite equip. interface protocol, reduces the complexity that normal communication is realized, shorten TD-SCDMA base station and evolve to the base stations the TD-LTE transformation time, guarantee the equipment normal communication in common networking to detect and adjust interface protocol.
