A FREQUENCY DOMAIN BASED TR-UWB RECEIVER

摘要

The frequency domain base TR-UWB receiver optimizes the signal-noise ratio by using the amplitude and phase obtained through the frequency transformation. The complex frequency component obtained through the frequency transformation process is divided into a real part and imaginary part before the autocorrelation process. Each component is computed through the autocorrelation. Each component is mapped to the signaling point on the complex plane and the auto correlation for each component is performed. Each component is mapped to the signaling point on the complex plane. By phase-shifting of the mapped component to the real-number axis the interference between signaling points is decreased.
