| 发明名称 | Method and system to adaptively cancel sinusoidal interference from a signal processing system | ||
| 摘要 | A method of canceling sinusoidal interference from a received signal includes identifying a block of signal-free data containing sinusoidal interference. A model of the significant interference in the selected data block is constructed, scaled to subsequent data blocks and used to remove sinusoidal interference signals from the overall received signal. | ||

| 主权项 | 1. A method of canceling sinusoidal interference from a signal to be processed, the method comprising the steps of: identifying sinusoidal interference from a received signal; generating a model of the identified sinusoidal interference; matching the model to the identified sinusoidal interference using a fitting operation, and cancelling the identified sinusoidal interference by subtracting the matched model from the identified sinusoidal interference, wherein the step of generating a model comprises the step of identifying sinusoidal interferences from a block of time-domain data samples of the received signal that are known to be interference-only. | ||
