    We propose a new multi-user detection of slow frequency hopping multicarrier direct- sequence code division multiple access technique (Multi-user detection of SFW MC DS-CDMA). The frequency hopping pattern are controlled by asset of constantweight code. Consequently, multirate communication can be implemented by selecting the correspandence set of constant-weight code. We assume the system operates in multipaths fading environment and a decorrelating receiver structure, The receiver has an explicit knowledge of the associzted ftequencyhopping (FH) pattems invoked. The system's performance is evaluated using Nakagami fading channels with numerical method. Furtlmmore the performance of the Multi-user detection of SFWMC DS-CDMA system is compared to the conventional Multi-user detection of direct-sequence code division multiple access system ( Multi-user detection of DSCDMA).
