Summary: | A synchronization unit for performing timing synchronization in the time domain includes storage, a multiplier, a signal analyzer, and a timing error estimation unit. The storage stores a reference signal. The multiplier calculates a sum of minus one product shift and a sum of plus one product shift based on the reference signal. The signal analyzer calculates left and right cross-correlation points based on the sum or minus one product shift and the sum of plus one product shift. The timing error estimation unit estimates a timing error of a received signal based on the left cross-correlation point and right cross-correlation point. |
