A RADIO RECEIVER APPARATUS FOR DETERMINING AND/OR COMPENSATING FOR A TIME DRIFT BETWEEN SAMPLE CLOCKS OF A TRANSMITTER AND A RECEIVER

摘要

A radio receiver system (30) comprises a radio receiver (41), a receiver sample clock (60), which is used for sampling a modulated base-band signal; and a timing correction unit (100). The timing correction unit (100) performs, in the frequency domain, a timing drift compensation between a transmitter sample clock (66) and the receiver sample clock (60), In one example context of implementation, the plural modulated radio frequency carriers have been modulated using Orthogonal Frequency Division Multiplexing (OFDM).
