MAC units for matched filters in DS-CDMA systems

High data rates in wireless radio environments are becoming common. Current system designs are inadequate to meet the speed requirements that are anticipated in the newer services. The computational complexities in the subsystems increase in direct proportion. We propose alternative multiply accumulate units for the pulse shaping filters that use a new representation for their coefficients. Consequently, these new structures are fast, efficient and consume less power. The filters proposed take into account constraints, such as, intersymbol interference, response characteristics etc. in their design methodology.
