This paper describes the design of a wideband spread spectrum radio using adaptive multiuser detection in an indoor wireless environment. System specifications are provided, and the feasibility of an integrated CMOS receiver implementation is discussed. The proposed receiver architecture uses a wideband analog front-end to reject out-of-band interference, and multiuser detection in the digital baseband to suppress interference from other system users.
