Adaptive crosstalk cancellation in dense wavelength division multiplexing networks
Electronics Letters, 1992 Laser frequency drift and close channel spacing in dense WDM networks can cause linear crosstalk.1 We propose to use the least mean squares (LMS) algorithm2 to adaptively cancel the crosstalk in an IM/DD receiver. This cancellation relaxes the laser frequency stabilization requirement and/or reduces the minimum channel spacing. A similar use of LMS was
