Abstract
A method for a wireless communication system is provided. The method includes analyzing a set of signal sources that are operably associated with a set of time domain windows. Often, the method periodically switches the association between the set of time domain windows and the set of signal sources in order to facilitate a determination of one or more signal paths generated by the signal sources.
Claims26
A method for a wireless communication system, comprising:
- generating a set of signal sources that are operably associated with a set of time domain windows, in which each signal source is associated with a different time domain window;
- and
- periodically switching the association between the set of time domain windows and the set of signal sources, in which the signal sources in the set become associated with new time domain windows, by alternating coding sequences while transmitting the set of signal sources from at least one transmitter.
A communications apparatus, comprising:
- means for generating a set of signal sources that are operably associated with a set of time domain windows, in which each signal source is associated with a different time domain window;
- and
- means for periodically switching the association between the set of time domain windows and the set of signal sources, in which the signal sources in the set become associated with new time domain windows, by alternating coding sequences while transmitting the set of signal sources from at least one transmitter.
A computer program product for wireless communication systems comprising:
- a computer-readable medium having non-transitory program code recorded thereon, the program code comprising:
- program code for generating a set of signal sources that are operably associated with a set of time domain windows, in which each signal source is associated with a different time domain window;
- and
- program code for periodically switching an association between a set of time domain windows and a set of signal sources, in which the signal sources in the set become associated with new time domain windows, to facilitate a determination of signal drift by alternating a signal sequence of the set of signal sources while transmitting the set of signal sources from at least one transmitter.

An apparatus for wireless communication comprising:
- a memory;
- at least one processor coupled to the memory, the at least one processor being configured to execute the following instructions:
- storing a set of signal sequences at a base station, the set of signal sequences to be applied to a set of signal sources associated with a set of time domain windows, in which each signal source is associated with a different time domain window;
- transmitting at least one of the signal sources of the set of signal sources from the base station;
- and
- periodically switching an association between the set of time domain windows and the set of signal sources, in which the signal sources in the set become associated with new time domain windows, to facilitate a determination of signal drift by alternating at least one of the signal sequences of the set of signal sources while transmitting the at least one of the signal sources of the set of signal sources from at least one transmitter.
