Abstract
A method of synchronizing a base station of a wireless communication system and a subscriber communication equipment located in the coverage area of the base station by compensating a sampling frequency offset in the subscriber equipment by interpolating input and/or output signals of a radio frequency part of the communication equipment to generate samples corresponding to the original symbol timing of the base station, and compensating the carrier frequency offset from the estimate of the sampling clock error.
Claims15
A method for synchronising a base station of a wireless communication system and a subscriber communication equipment located in the coverage area of the base station, comprising:
- compensating a sampling frequency offset in the subscriber equipment by interpolating at least one of input and output signals of a radio frequency part (30) of the communication equipment to generate samples corresponding to an original symbol timing of the base station, and
- compensating a carrier frequency offset from the estimate of a sampling clock error.
A device for synchronising a base station of a wireless communication system and a subscriber communication equipment located in the coverage area of the base station, comprising:
- an interpolator (48) interpolating input and/or output signals of a radio frequency part of the communication equipment to generate samples corresponding to an original symbol timing of the base station, and
- calculating means (51) for compensating a carrier frequency offset from the estimate of a sampling clock error.
