摘要：
A joint carrier frequency offset (CFO) and channel estimation technique is presented for burst mode OFDM systems. It employs the non-linear recursive least squares (NL-RLS) algorithm working in time domain and in decision directed mode. When compared with other techniques, this approach functions without the aid of pilot tones in the OFDM data symbols, maintains a reasonable complexity, and provides a superior performance, which is shown to be insensitive to decision errors even at low SNR.
