Abstract
A method for coexistence with a pulsed interference source in a communications network includes receiving a communications signal, determining a first portion of the communications signal that is affected by the pulsed interference source, blanking the first portion of the communications signal, and processing the communications signal.
Claims20
A method for coexistence with a pulsed interference source in a communications network, the method comprising:
- receiving a communications signal at a receiver of the communications network;
- determining a first portion of the communications signal that is affected by the pulsed interference source;
- comparing a size of the first portion to a threshold value;
- blanking the first portion of the communications signal;
- and
- processing the communications signal,
- wherein blanking the first portion is performed only when the size is greater than the threshold value.
A communications system, the system comprising:
- a receiver that receives a communications signal;
- a blanking module that determines a first portion of the communications signal that is affected by a pulsed interference source and blanks the first portion of the communications signal;
- and
- a processing module that processes the communications signal after the first portion has been blanked,
- wherein the blanking module compares a size of the first portion to a threshold value, and
- wherein blanking the first portion is performed only when the size is greater than the threshold value.
A non-transitory computer readable medium with computer executable instructions stored thereon which, when executed by a processor, perform the following method:
- for a communications signal received at a receiver of a communication node, determining a first portion of the communications signal that is affected by a pulsed interference source;
- comparing a size of the first portion to a threshold value;
- blanking the first portion of the communications signal;
- and
- processing the communications signal,
- wherein blanking the first portion is performed only when the size is greater than the threshold value.
A method for coexistence with a pulsed interference source in a communications network, the method comprising:
- receiving a communications signal at a receiver of the communications network;
- determining a first portion of the communications signal that is affected by the pulsed interference source, wherein determining the first portion of the communications signal includes dividing a transmission time interval (TTI) into a plurality of subunits;
- determining energy values for the subunits;
- determining an average energy for the subunits;
- calculating ratios between the energy value for each subunit and the average energy;
- comparing the ratios to a threshold value;
- and
- when a ratio exceeds the threshold value, blanking the first portion of the communications signal by blanking the subunit associated with the ratio that exceeds the threshold value;
- and
- processing the communications signal.
