Patent ID: 8149758

Claim:
A wireless communication system for executing transmission and reception of a radio signal among communication terminals via a plurality of base stations connected to a cable network, comprising a first of the base stations that performs an AD conversion on a radio signal received via an antenna from one of the communication terminals without demodulation, packetizes the AD-converted radio signal into packet data, and transmits the packet data over the cable network to a second of the base stations that performs DA conversion on the packet data received over the cable network from the first base station, transforms the DA-converted packet data into a radio signal without modulation, and transmits the radio signal to another communication terminal via the antenna, an I channel signal and a Q channel signal both being extracted from the radio signal received via the antenna on a same time axis over a plurality of sampling periods, and being subjected to the AD conversion without demodulation, and at a time of packetizing the I channel signal and the Q channel signal, sampled values of an I channel and sampled values of a Q channel being alternately arranged in a time sequential order.
