Data-Aided Joint Estimation of Carrier Frequency Offset and Frequency-Selective Time-Varying Channel
16 years 1 months ago
—The issue of data-aided joint carrier frequency offset (CFO) and channel estimation is investigated in the presence of a rapidly time-varying frequency-selective channel. We der...
