Abstract :
Proposed is an improved blind carrier frequency offset (CFO) estimator suitable for Multi-Band OFDM Ultra Wideband (MB-OFDM UWB) system. By exploiting the conjugate symmetry of the physical layer convergence protocol (PLCP) the need for training symbols can be avoided and estimation performance is improved as well. Computer simulations show that the proposed method achieves better estimation performance than existing method.
