| Abstract: |
| The detection of Chirp-COTR-UWB signal using Active Spectrum Compressi
on(ASC) technology is studied. On the basis of the current detecting structure a
nd th
e characteristic of COTR signal, a new modified detection method based on severa
l symbols feedback balance accumulation is proposed.The theoretical analysis an
d simulation result show that the new method not only keeps the simplicity of th
e inhere structure but also achieves the purpose of template-purification. It ca
n effectively improve the system performance. |
| Key words: UWB chirp signal COTR feedback balance accumulation detection method |
