SYSTEMES, PROCEDES ET APPAREILS POUR UNE TECHNIQUE DE GENERATION D'UN LONG RETARD POUR LA DETECTION SPECTRALE D'UNE RADIO COGNITIVE |
摘要 |
<p>#CMT# #/CMT# The method involves providing an analog current input signal and an analog delayed signal that lags behind the analog current input signal by a preset time delay. The analog current input signal is correlated with the analog delayed signal to generate correlation data. A signal type e.g. IEEE 802.11aorthogonal frequency division multiplexing (OFDM) signal, is detected based on the correlation data that matches with a signature of the signal type, where the signature is associated with the preset time delay. #CMT# : #/CMT# An independent claim is also included for a system for analog auto-correlation. #CMT#USE : #/CMT# Method for analog auto-correlation (AAC) for use in wireless communications for spectrum sensing of cognitive radio. #CMT#ADVANTAGE : #/CMT# The method performs analog auto-correlation (AAC) in an analog domain in an AAC system such that the system has low-power requirements and performs real-time computation. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a long delay generator implemented with RAM cells. 106 : Long delay generator.</p> |
