“…In SDSS system [7], the received signal is multiplied by a reference PN sequence over particular step size (single chip) and is accumulated subsequently after each step [8], the result of which is used to make a synchronization decision by comparison with a threshold. Such multiply and integrate type of correlation structure can be implemented through Multiply and Accumulate (MAC) operation in digital domain as shown in Fig.1.…”

“…In synchronization terms, this is known as Data-Aided (DA) synchronization [6 ]. In [7], the received PN signal plus noise is multiplied by a local PN reference over a particular step size (single chip) and is accumulated subsequently over each step [8], the result of which is used to make a synchronization decision by comparison with a threshold. Such multiply and integrate type of correlation structure can be implemented in digital domain through Multiply and Accumulate (MAC) operation as shown in Fig.l (1) and T d = NT c , N is the length of the PN Sequence and T c is the chip period.…”

Code Division Multiple Access (CDMA) is a widely used multiple access technique in cellular and military communication systems. In Direct Sequence Spread Spectrum (DSSS) communications, a Pseudo Noise (PN) spreading code is typically applied to the data samples prior to transmission. Synchronization of this unique code with the incoming data samples forms a significant step in the data reception process. Single Dwell Serial Search (SDSS) and Matched Filtering are some of the types of CDMA code synchronization techniques. This paper presents the design and comparison of SDSS technique & Digital Matched Filter (DMF), and shows the effectiveness of DMF for rapid synchronization. It further presents Recursive Digital Matched Filter (RDMF) which reduces resource utilization and the obtained results clearly shows that the proposed RDMF has the characteristics that are highly suitable for code synchronization in CDMA application compared to conventional methods.
