Abstract
This paper presents a novel receiving scheme with combining phase error tracker (PET) and MMSE equalizer for multi-band ultra wideband (MB-UWB). A low complexity phase error tracker is developed to track the phase error caused by carrier frequency offset (CFO) and sampling clock offset (SCO), which will cause fatal error in coherent OFDM demodulation. The proposed joint scheme makes the receiver more robust to CFO and SCO effects and can suppresses the error rate at low SNR and high data rate receiving. With through MB-UWB simulation, the proposed scheme contributes 1.36~7.25 dB gain in SNR for 8% packet error rate (PER) specification in different transmission modes. Furthermore, the low complexity algorithm can benefit the low area and low power design for wireless applications.
