An FFT-based Acquisition Scheme for DS-CDMA Systems

By Re P. Almeida Member, Rui Dinis and Francisco B. Cercas

Abstract

Abstract — This paper introduces an efficient acquisition/correlation technique for DS-CDMA systems using a frequency-domain approach employing TCHbased training blocks (Tomlison, Cercas and Hughes). The classical time-domain active acquisition technique is compared with the proposed passive matched-filter type frequency domain technique. Moreover using the fact that an N-point Discrete Fourier Transform (DFT) can be partitioned into M smaller DFTs, we present a procedure for simultaneous decoding/despreading and synchronization that switch between 16 bit-length and 256 bit-length cyclic codes thus providing code rate variability
