[NOTES]:
3. IrDA Control system uses 16PSM coding scheme over 1.5MHz sub-carrier. See IrDA Control Physical Layer Link
Specification for the details of coding scheme and pulse characteristics.
4. See Figure 5.1 (below) for the viewing angle definition.
5. An in-band optical signal is a pulse/sequence where the peak wavelength λp, is defined as 850nm < λp < 900nm,
and the pulse characteristics are compliant with the IrDA Control Physical Layer Link Specification.
