Abstract :
In CDMA (Code Division Multiple Access) systems, a baseband digital bandlimiting filter is required to achieve zero Inter-Symbol Interference (ISI). This paper presents an efficient implementation of a CDMA 2000 baseband filter based on a Reconfigurable Multiplier Blocks (ReMB). The foundations of the new structure are a modified Interpolated Finite Impulse Response (IFIR) structure and rounding technique. This choice of ReMB yields a multiplier free structure with less implementation resources than previous designs.
