Method and system for interactive channel equalization
摘要:
A method and system for interactive channel equalization uses channel status information included in data packets. The system includes a first station adapted to transmit a first data packet including a channel status information segment over a radio communication channel as a first signal. A second station in the system includes a static pre-equalizer and an adaptive equalizer. The second station is adapted to receive the first signal and adaptively equalize the first signal using the adaptive equalizer and the channel status information to create a post hoc status estimate of the channel. The second station is further adapted to transmit a second data packet over the channel as a second signal, where the second signal is pre-equalized by the pre-equalizer using the post hoc status estimate of the channel. The method and system thus enable parameters of the channel equalization to be adjusted in real-time in response to varying channel conditions.
