Constructor Detail

OchSignal

public OchSignal(GridType gridType,
                 ChannelSpacing channelSpacing,
                 int spacingMultiplier,
                 int slotGranularity)

Creates an instance with the specified arguments. It it recommended to use Lambda.ochSignal(GridType, ChannelSpacing, int, int) unless you want to use the concrete type, OchSignal, directly.

Parameters:

gridType - grid type

channelSpacing - channel spacing

spacingMultiplier - channel spacing multiplier

slotGranularity - slot width granularity

OchSignal

public OchSignal(LambdaResourceAllocation alloc,
                 org.onlab.util.Frequency maxFrequency,
                 org.onlab.util.Frequency grid)

Create OCh signal from lambda resource allocation.

Parameters:

alloc - lambda resource allocation

maxFrequency - maximum frequency

grid - grid spacing frequency

OchSignal

public OchSignal(org.onlab.util.Frequency centerFrequency,
