The growing demand for capacity in wireless communications is the major motivational force behind improvements in established networks and development of new communication technologies - direct sequence code division multiple access (DSCDMA) being one of them. Capacity calculations show that DS-CDMA, the underlying technology for 3rd generation wireless communication offers greater capacity than the combination of time and frequency division multiple accesses, used in the 2G era. This, combined with the emerging concept of software radio motivated us to aim at a real-time DSP board implementation of DS-CDMA receiver that could combat all wireless channel effects. This paper presents a comprehensive review of the implementation details followed by an extensive analysis of receiver performance under varied channel conditions and system parameters.
