| Abstract: |
| According to the signal reconnaissance of mobile communication system in a certa
in area, a top design of low SNR WCDMA mobile communication signal receiving and
processing system in complex environment is introduced.An optimized cell search
s
cheme is adopted by using differential coherent accumulation and RS decoder and
the performance of low SNR WCDMA signal processing is improved. Computation and
experiment confirm the effectiveness of the optimized scheme. |
