The rapid proliferation of the Internet has been driving communication networks closer and closer to their limits, while available bandwidth is disappearing due to an ever-increasing network load. Over the past decade, optical fiber communication technology has increased per fiber data rate from 10 Tb/s to exceeding 10 Pb/s. The major explosion came after the maturity of coherent detection and advanced digital signal processing (DSP). DSP has played a critical role in accommodating channel impairments mitigation, enabling advanced modulation formats for spectral efficiency transmission and realizing flexible bandwidth. This book aims to explore novel, advanced DSP techniques to enable multi-Tb/s/channel optical transmission to address pressing bandwidth and power-efficiency demands. It provides state-of-the-art advances and future perspectives of DSP as well.

We examine the role of social networks in job-related migration. With over 130 million rural labors migrating to the city each year, China is experiencing the largest internal migration in the human history. Based on the 2006 China Agricultural Census, we show that individual migration decisions vary greatly across villages; but migrants from the same village tend to cluster in the same destination and occupation. After using China's one-child policy as instruments for neighbor migration, we conclude that the clustered migration is most likely driven by same-origin villagers helping each other in moving cost and job search at the destination.
