Implementation of an all-digital DS-CDMA receiver-chip synchronization for an orthogonally coded cellular CDMA system

The authors propose an all-digital code tracking scheme for a bandlimited cellular direct-sequence code-division-multiple-access (DS-CDMA) system, which uses bandlimited Nyquist chip pulse shaping and orthogonal coding. The code tracking loop has a decision-directed noncoherent structure to handle the orthogonally coded DS-CDMA signals. The performance of the tracking loop is derived analytically.<
