摘要：
Digital signal processing techniques used in conjunction with phase-diversity coherent optical receivers are presented in this paper. These techniques enable coherent detection and mitigation of optical impairments introduced in transmission. The main advantage of this approach is that the optical impairments can be handled in the digital domain instead of analog or optical domains, thus reducing various hardware requirements (e.g. dispersion compensating fibers). Dispersion compensation and carrier phase estimation techniques are discussed in detail.
