| Abstract: |
| Data transmission of low BER（Bit Error Rate） without GI(Guard Interval) can ef
fectively reduce the in
formation redundancy and is important to save the band of system and raise the d
ata rate. IT（Implicit Training） is added to data directly to cancel the GI. Th
e int
erferences are canceled by cutting and pasting after the circular correlation ch
annel estimation algorithm is deduced. Comparison between different channel
estimation algorithms shows that the new algorithm has acceptable performance
and low complex
ity. |
