Sync bursts for frequency offset compensation |
摘要 |
A method ( 500 ) and system for compensation of frequency offset between a first transceiver ( 102 ) and a second transceiver ( 104 ) in wireless communication are disclosed. The compensation of the frequency offset between two or more transceivers ( 102, 104 ) is achieved using frequency synchronization bursts. These bursts contain information about the frequency offset. The frequency synchronization bursts are transmitted by the first transceiver at a range of frequencies above and below its carrier frequency ( 502 ). A second transceiver that receives at least one of these bursts ( 504 ) determines the frequency offset ( 504 ), and adjusts its frequency to match the frequency of the first transceiver ( 508 ). Thereafter, the second transceiver may enter a low power sleep mode ( 510 ) in order to reduce its power consumption. The second transceiver returns to active mode ( 512 ) just before the start of the transmission of the data packets ( 514 ). |
