The receiver comprises a demodulator, symbol synchronization unit, frequency transform processor, and coarse frequency offset detector. The demodulator generates sampled symbols. The symbol synchronization unit has correlators, which receives the sampled symbols, and a correlation detection processor. Each correlator auto correlates each sampled symbol, and the correlation detection processor determines a start point of each symbol. The frequency transform processor receives the sampled symbols and performs a frequency transform on each symbol. The coarse frequency offset detector includes a pilot data filter, which includes taps corresponding to a value and spacing of the pilot pattern of the symbols and arranged to receive as an input the frequency domain symbols from the frequency transform processor, and a coarse frequency offset detect processor, which is arranged to detect a coarse frequency offset output from the pilot data filter."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Receiver and method","description":"A receiver for detecting and recovering data from Orthogonal Frequency Division Multiplexed (OFDM) symbols.
