摘要：
OFDM requires precise channel estimates which are effortlessly acquired by assuming perfect-synchronization of frequency and phase. However, significant carrier frequency offset (CFO) as well as phase noise (PHN), that generates considerable inter-carrier interference (ICI) might be found in a practical receiver, which a standard OFDM channel-estimator could not tolerate. By having prior statistical-knowledge of phase-noise (PHN) from the data sheets, a maximal joint estimator of CFO, channel impulse-response(CIR), and PHN algorithm (JCPCE) was presented in this paper, which effectively realized by applying fast Fourier Transform (FFT).
