碩士 / 聖約翰科技大學 / 電子工程系碩士班 / 101 / In this thesis , we use thedirect sequence code division multipe access (DS-CDMA) system and underwater channel model [1] for our research. There are several important features in the warm shallow underwater channel, such as time-varying and multi-path effects. In this thesis, we use the Rake rerceiver and decision feedback equalizer (DFE) to combat multi-path effect, which is caused by the underwater channel . Further , the multiuser detection (MUD) is used for the DS-CDMA system to obtain lower bit error rate.
