Abstract
A radio base station apparatus according to the invention includes an information monitoring sectionand transmitter sectionsto. Each of the transmitter sectionsto in includes a delay control sectiona data control sectiona delay adjustment sectionand an RF sectionThe information monitoring sectionmonitors the operation status of the data control section of each of the transmitter sectionsto. The information monitoring sectioncontrols the data control sectionaccording to the operation status monitored. The data control sectiongenerates a multiplexed signal of a spread delay adjustment signal and a spread main signal. The multiplexed signal goes through the delay adjustment section and RF section, and is outputted via an antenna element. At the same time, the delay control sectioncompares the signal obtained by multiplexing the delay adjustment signal in the data control sectionwith a transmitting signal detected from the RF section to thereby calculate a transmission delay time.
