Abstract
A wireless communication system includes distributed units communicating with a terminal device and a central unit connected to the distributed units and receiving and processing signals from the distributed units. The central unit includes a host function unit to pre-notify the distributed units if a received signal from the terminal device is a target of coordination between distributed units, hard/soft determination units configured to separate received signals from the distributed units into a hard decision value and a soft decision value based on presence or absence of coordination between the distributed units, transmit the hard decision value to the host function unit as is, and transmit the soft decision value to a signal combining unit, the signal combining unit combines soft decision values output from the hard/soft determination units and outputs a combined soft decision value, and a decoding unit performs decoding using the soft decision value output from the signal combining unit.
