System and method for detecting a fault in a multiple receiver system
View Patent ↗A system and method for receiving output signals from each receiver of multiple receivers, the output signals generated based on receipt of a same transmission; incrementing a count value associated with each receiver based on the output signals; and determining whether a fault in a receiver exists based on the associated count values of the receivers.
1. A method for detecting a fault in a multiple receiver system, comprising:
receiving output signals from each receiver of the multiple receivers, the output signals generated based on receipt of a same transmission and including at least one of magnitude information and rake finger information for each receiver;
incrementing a count value associated with at least one receiver if the output signals of the at least one receiver indicate a threshold has been reached by the at least one receiver based on the at least one of the magnitude information and the rake finger information of the at least one receiver; and
determining whether a fault in a receiver exists based on the associated count values of the receivers.
2. The method of claim 1 , wherein the incrementing step increments the count value associated with the receiver based on magnitudes of the output signals.
3. The method of claim 1 , wherein
the output signals include input path information for each receiver, and
the incrementing step includes incrementing the count value of at least one receiver when the output signals of the at least one receiver indicate that a signal has been received by the at least one receiver based on the input path information of the at least one receiver.
4. The method of claim 1 , wherein
the output signals include timing information for each receiver, and
the incrementing step includes incrementing the count value of at least one receiver when the output signals indicate that a signal has been received by the at least one receiver based on the timing information of the at least one receiver.
5. The method of claim 1 , wherein the determining step determines that the fault exists in the receiver when the associated count value differs by more than a set amount from the count values associated with the other receivers in the multiple receiver system.
6. The method of claim 1 , further comprising:
sending an alarm message when the determining step determines a fault is present.
7. A system for detecting a fault in a multiple receiver system comprising:
a control unit connected to multiple receivers, the control unit receives output signals from each receiver of the multiple receivers, the output signals generated based on receipt of a same transmission and including at least one of magnitude information and rake finger information for each receiver; increments a count value associated with at least one receiver if the output signals of the at least one receiver indicate a threshold has been reached by the at least one receiver based on the at least one of the magnitude information and the rake finger information of the at least one receiver; and determines whether a fault in a receiver exists based on the associated count values of the receivers.
8. The system of claim 7 , wherein
the control unit further increments the count value associated with the receiver based on magnitudes of the output signals.
9. The system of claim 7 , wherein
the output signals include input path information for each receiver, and
the control unit further increments the count value of at least one receiver when the output signals of the at least one receiver indicate that a signal has been received by the at least one receiver based on the input path information of the at least one receiver.
10. The system of claim 7 , wherein
the output signals include timing information for each receiver, and
the control unit further increments the count value of at least one receiver when the output signals indicate that a signal has been received by the at least one receiver based on the timing information of the at least one receiver.
11. The system of claim 7 , wherein
the control unit further determines that the fault exists in the receiver when the associated count value differs by more than a set amount from the count values associated with the other receivers in the multiple receiver system.
12. The system of claim 7 , wherein
the control unit sends an alarm message when the determining step determines a fault is present.
