Abstract :
We present and analyze several pre- and post-compensation algorithms for bandwidth-limited optical signal on mitigation towards inter-symbol-interference (ISI) or joint ISI and inter-channel-interference (ICI) impairments. Experimental results and support to higher-order modulation format are also demonstrated.
