| Abstract: | The multi-mode processing of wireless base-band signal is the development trend of broadband mobile communications at present. In the WCDMA systems, the typical base-band signal processing is the cross-correlation of finite sequences. A multi-path detection method in base-band signal processing, which uses the Fast Fourier Transformation (FFT), is proposed in this paper. It has the same framework of FFT operation in LTE base-band signal processing and can realize the multi-mode resource sharing of WCDMA and LTE base-band. The simulation results demonstrate that the proposed method can meet the performance and computation demands of practical application. |
