METHOD AND OFDM RECEIVER WITH MULTI-DIMENSIONAL WINDOW PROCESSING UNIT FOR ROBUSTLY DECODING RF SIGNALS
摘要
The invention enhances channel correction techniques for orthogonal frequency division multiplexing (OFDM) systems so that higher effective data rates can be achieved with a minimal processing load. OFDM channel values determined due to known sequences in one domain can be used to seed solution matrices for channel value determination in other domains. This method can be applied to multiple-input multiple-output (MIMO) systems in order to deal with signal distortion while maintaining a reasonable processor loading profile. In another embodiment, a method to optimize channel partitioning during channel estimation processing in an ultra-wide band (UWB) OFDM wireless communications network includes creating a plurality of windows across a time-frequency channel plane, adaptively sizing the plurality of windows, and merging the plurality of windows.
