A dynamic phase and frequency recovery (DPR & DFR) is proposed for power reduction and performance improvement. By the DPR, signal sampling rate is reduced from Nyquist rate (or higher) to the symbol rate, resulting in reduced ADC circuit power. By the DFR, data is recovered from less-interfered signals. In the MB-OFDM UWB system, the simulations show that the system improves 2.3 dB SNR and reduce...
