Abstract
An apparatus comprising at least two controllers each providing control information for controlling phase or frequency of a digital signal, a combiner for combining control information from the at least two controllers to combined control information and a phase rotator for adjusting, by using phase rotation, one or more of the phase and the frequency of the digital signal on the basis of the combined control information.
Claims19
An apparatus, comprising:
- at least two controllers configured to provide control information to control a phase or a frequency of a digital signal;
- a combiner configured to combine the provided control information from the at least two controllers into combined control information;
- and
- a phase rotator configured to adjust, by using phase rotation, at least one of the phase and the frequency of the digital signal on the basis of the combined control information.
A mobile station, comprising:
- at least two controllers configured to provide control information to control a phase or a frequency of a digital signal;
- a combiner configured to combine the provided control information from the at least two controllers into combined control information;
- and
- a phase rotator configured to adjust at least one of the phase and the frequency of the digital signal by using phase rotation on the basis of the combined control information.
An apparatus, comprising:
- first control means for providing first control information for adjustment of a phase or a frequency of a digital signal;
- second control means for providing second control information for adjustment of the phase or the frequency of the digital signal;
- combining means for combining the first and the second control information into combined control information;
- and
- rotating means for rotating at least one of the phase and the frequency of the digital signal by using phase rotation on the basis of the combined control information.
A method, comprising:
- providing first control information to adjust a phase or a frequency of a digital signal;
- providing second control information to adjust the phase or the frequency of the digital signal;
- combining the first and the second control information into combined control information;
- and
- rotating at least one of the phase and the frequency of the digital signal by using phase rotation on the basis of the combined control information.
A computer program embodied on a computer-readable medium, the program controlling a processor to perform:
- providing first control information to adjust a phase or a frequency of a digital signal;
- providing second control information to adjust a phase or a frequency of the digital signal;
- combining the first and the second control information into combined control information;
- and
- rotating at least one of the phase and the frequency of the digital signal by using phase rotation on the basis of the combined control information.
