| Abstract: |
| An algorithm which is based on FFT and can be implemented with DSP is provided to search the midamble code in ad-hoc networks based on the slot structure of UTRA TDD LCR.The implementation of multipath searching is also provided.The algorithm makes full use of the characters of DSP and the operating efficiency of the algorithm is much higher than that of the conventional MF algorithm. |
