This paper proposes flexible hardware structures of spreading and modulation for multi-mode CDMA systems. The proposed flexible structures supporting IS-95, CDMA2000 and WCDMA, include a pseudo noise code generator, a channelization code generator and a control circuit for signal flow control. The proposed design has been modeled by VHDL and synthesized using the Faraday 0.25 mum standard cell library. The synthesis results show the area reduction about 24.7% compared with the original code generators
