Code Division Multiple Access (CDMA) is a multiple access technique widely used in cellular and military communication systems. In Direct Sequence Spread Spectrum (DSSS) communications, data samples are embedded inside Pseudo Noise code (PN code) prior to transmission. Synchronization of this unique code with the incoming data samples forms an important step in data recovery. Single Dwell Serial Search (SDSS) and matched filtering are some of types of the CDMA code synchronization techniques. This paper presents design and implementation of Recursive Digital Matched Filter (RDMF) for code synchronization in CDMA.
