Abstract
The subject matter disclosed herein relates to suppressing the effects of multipath signals. For an example, a signal comprising at least one binary offset carrier (BOC) modulation signal is received. The BOC modulation signal is modulated with a pseudorandom noise sequence comprising a plurality of chips, wherein each of the chips has a set interval. The received signal is correlated with portions of the plurality of chips to provide a power signal and to remove at least a portion of a multipath component in the received signal from the power signal. The portions of the chips are less than the set interval.
Claims37
A method comprising:
- receiving a signal comprising at least one binary offset carrier (BOC) modulation signal, said BOC modulation signal being modulated with a pseudorandom noise sequence and comprising a plurality of chips, each of said chips having a set interval;
- and
- correlating said received signal with portions of each chip of said plurality of chips to provide a power signal, said portions of said chips being less than said set interval to remove at least a portion of a multipath component in said received signal from said power signal.
An article comprising:
- a storage medium, said storage medium comprising machine-readable instructions stored thereon which, if executed by a computing platform, are adapted to cause said computing platform to:
- receive a signal comprising at least one binary offset carrier (BOC) modulation signal, said BOC modulation signal being modulated with a pseudorandom noise sequence and comprising a plurality of chips, each of said chips having a set interval;
- and
- correlate said received signal with portions of each chip of said plurality of chips to provide a power signal, said portions of said chips being less than said set interval to remove at least a portion of a multipath component in said received signal from said power signal.
A subscriber station comprising:
- a receiver to receive a signal comprising at least one binary offset carrier (BOC) modulation signal, said BOC modulation signal being modulated with a pseudorandom noise sequence and comprising a plurality of chips, each of said chips having a set interval;
- and
- a correlator to correlate at least in part said received signal with portions of each chip of said plurality of chips to provide a power signal, said portions of said chips being less than said set interval to remove at least a portion of a multipath component in said received signal from said power signal.
A system, comprising:
- a position determination entity;
- and
- a subscriber station comprising a receiver to receive a signal comprising at least one binary offset carrier (BOC) modulation signal, said BOC modulation signal being modulated with a pseudorandom noise sequence and comprising a plurality of chips, each of said chips having a set interval, and a correlator to correlate at least in part said received signal with portions of each chip of said plurality of chips to provide a power signal, said portions of said chips being less than said set interval to remove at least a portion of a multipath component in said received signal from said power signal.
