碩士 === 國立交通大學 === 電子研究所 === 81 === With the tremendous growing demand in personal communica- tion, the spread spectrum technique is drawing much attention gradually. In this thesis, we focused on the design of a Di- rect Sequence-Binary Phase Shift Keying(DS-BPSK) spread spec- rum transceiver. A digital VLSI architecture to implement the transceiver was proposed. Various design aspects of the arc- hitecture including Gold code structured pseudo-noise genera- tor, digital Costas loop, and serial search acquisition meth- od were carefully studied and simulated. Overall performance of the design was evaluated through the full simulation. We found that the advantages of our architecture includes easy implementation and fast acquisition. However, the performance was not as good as we wish. The reasons were explored and some future works were presented in the final part of this thesis.
