  • Method and system for reducing out of band radiation in orthogonal frequency division multiplexing systems
    Patent number: 8483300
    Abstract: The various embodiments herein provide a method and system for reducing Out of Band Radiation in Orthogonal Frequency Division Multiplexing (OFDM). The method includes transmitting a plurality of signals with a plurality of modulated symbols on each subcarrier. The method includes introducing a controlled amount of correlation among the consecutive modulated symbols across time. Further the method includes removing the controlled amount of correlation among the plurality of modulated symbols. The method also includes reducing an out of band radiation in OFDM. The system for reducing Out of Band Radiation in Orthogonal Frequency Division Multiplexing (OFDM) includes a transmitter to transmit one or more signals with a plurality of modulated symbols on each subcarrier. The system includes a transmitter with digital filters and a receiver. The receiver includes a Maximum Likelihood Sequence Detector (MLSD) to remove the controlled amount of correlation among the plurality of modulated symbols.
