Abstract

A novel algorithm called partial transmit sequence-active interference cancellation (PTS-AIC) is proposed to implement interference avoidance functionality in an ultra-wideband (UWB) OFDM device. It can be considered as another application of the PTS algorithm that has been applied to an OFDM transmission to reduce its peak-to-average power ratio. Specifically, PTS-AIC with adjacent subblock partitioning and interleaved subblock partitioning are proposed and compared. It is shown that the PTS-AIC can provide deep notch on the interference band. The x%-excess interference power is defined as a performance measure for PTS-AIC. Compared to existing approaches, PTS-AIC provides more flexibility in parametrizing the algorithm for trade-off between performance and complexity.
