摘要：

提出了基于多频带正交频分复用系统的帧同步信号检测方法,以识别微微网和辅助信号符号的定时。该检测方法对所接收与预期存储在接收端的12或24个包/帧同步符号进行相关联计算,从以上关联值的统计结果中选择最有可能的时频码给予接收端解码。测试结果显示,系统的稳定性能有大幅提高

关键词: 多频带正交频分复用, 时频码, 帧同步

Abstract:

Wireless local area network communication equipment is usually based on an ad hoc network operation.A frame synchronization detection method is proposed for multi-band orthogonal frequency division multiplexing (MB-OFDM) system to identify piconet and symbols timing.The detection method is based on having correlation of the received and expected local storage of 12 or 24 packages/frame synchronization symbols.The most possible time-frequency code is chosen from the statistics of these correlation results for receiver decoding.The test results show that system stability is greatly improved.

Key words: MB-OFDM;time frequency code;frame synchronization
