Chapter three is our main block and work , it summarized the high speed physical layer extension ( ieee 802 . lib ) standards , explained in details the complementary code keying ( cck ) modulation and demodulation techniques , and then explained and developed the fast walsh transform ( fwt ) that has been used to increase the data rates of these protocols
第三章是论文的主要组成部分，也是本研究工作的重点。这一章总结了高速物理层标准增强版( 1eee802 11b ) ，并详细介绍了互补码键控( cck )调制解调技术，描述并改进了用于提高数据速率的快速walsh变换( fwt ) 。
