Gonstant-modulus algorithm （CMA） based blind multiuser receiver is proposed for multiuser detection of DS-CDMA UWB systems in a realistic indoor channel. we propose to adopt a two stage receiver, in the first stage, partial ISI and MAI suppression is achieved by exploiting the desired user signature structure properties; in the second stage, based on CMA, the residual MAI and the ISI are removed, and the desired symbols are reliably recovered. Computer simulations show that, the proposed detect...
