RECEIVER WINDOW SHAPING IN OFDM TO MITIGATE NARROWBAND INTERFERENCE
摘要
A receiver window for symbol extraction is provided. A symbol is spread across a plurality of sub-carriers of a frequency band for transmission. If the frequency band is affected by narrowband interference, the receiver window concentrates the narrowband interference energy to minimize its effect on distant sub-carriers within the frequency band. The receiver window is shaped for extracting the symbol from the frequency band, wherein the receiver window has a starting point before the start of the symbol. The receiver window overlaps a previous receiver window for the previous adjacent symbol on the same frequency band. The receiver window is shaped by overlapping and adding a channel impulse response segment from a zero-padded portion of the symbol to the beginning of the symbol and overlapping and adding a second portion from the previous zero-padded symbol (from the same frequency band) to the end of the symbol.
