Abstract
Devices, systems, and methods are provided for reducing interference of light detection and ranging (LIDAR) emissions. A vehicle may identify location information associated with a location of the vehicle. The vehicle may select, based on the location information, a modulation code associated with a LIDAR photodiode of the vehicle. The vehicle may emit, using the LIDAR photodiode, one or more LIDAR pulses based on the modulation code.
Claims18
A method for pulse modulation, the method comprising:
- identifying, by at least one processor of a vehicle, first location information associated with a first location of the vehicle and second location information associated with a second location of the vehicle;
- selecting, by the at least one processor, based on the first location information, a first modulation code associated with a light detection and ranging (LIDAR) photodiode of the vehicle and a second modulation code for the LIDAR photodiode based on the second location information;
- and
- emitting, by the LIDAR photodiode, one or more LIDAR pulses based on the first modulation code or the second modulation code,
- wherein the first modulation code is orthogonal or quasi-orthogonal to the second modulation code.
A device for pulse modulation, the device comprising memory coupled to at least one processor, the at least one processor configured to:
- identify first location information associated with a first location of a vehicle and second location information associated with a second location of the vehicle, the vehicle comprising the device;
- select, based on the first location information, a first modulation code associated with a light detection and ranging (LIDAR) photodiode of the vehicle and a second modulation code for the LIDAR photodiode based on the second location information;
- and
- cause the LIDAR photodiode to emit one or more LIDAR pulses based on the first modulation code or the second modulation code,
- wherein the first modulation code is orthogonal or quasi-orthogonal to the second modulation code.
A system for pulse modulation, the system comprising:
- memory coupled to at least one processor, the at least one processor configured to:
- identify first location information associated with a first location of a vehicle and second location information associated with a second location of the vehicle, the vehicle comprising the memory coupled to the at least one processor;
- and
- select, based on the first location information or the second location information, a first modulation code associated with light detection and ranging (LIDAR) pulses and a second modulation code for the LIDAR photodiode based on the second location information;
- and
- a LIDAR photodiode configured to:
- emit one or more LIDAR pulses based on the first modulation code or the second modulation code,
- wherein the first modulation code is orthogonal or quasi-orthogonal to the second modulation code.
