摘要： There is provided a main unit and a distributed antenna system including the same. The main unit for constituting a distributed antenna system that receives a base station signal from at least one base station, transmits the base station signal to at least one user terminal, and includes a plurality of main units, the main unit includes: a first receiver for receiving a first group of base station signals; a second receiver for receiving a second group of base station signals from another main unit; a signal combiner for combining the first and second groups of base station signals; and a delay compensator for compensating for time delay corresponding to a path between the main unit and the other main unit with respect to the first group of base station signals before combining the first and second groups of base station signals.
