We present a novel dual channel identification approach for fast time-varying wireless communication systems. Unlike traditional channel methods that rely on training symbols, we propose a bent-pipe feedback mechanism which requires the mobile unit to send portions of its received signal back to the transmitter for wireless channel identification. Using a filter-bank decomposition concept, we introduce an effective algorithm that can identify both the forward and the reverse channels based only on this feedback information without reverse-link training. This new method has great potential in the design of future high data rate wireless communication systems
