Timing drift compensation in wireless packet-based systems |
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). |
