Preamble-based joint frame and frequency synchronization for OFDM — WMAN systems

Orthogonal frequency-division multiplexing (OFDM) is a well known multi-carrier digital modulation scheme in which a transmitted data is split into multiple streams that are modulated at different frequencies. The OFDM system is very sensitive to frame and frequency synchronization errors. In this paper, we propose a preamble for frame and frequency… CONTINUE READING
