摘要： A mobile station transmitted signal received at array antenna 11 is converted into an intermediate frequency signal in frequency conversion section 12, and converted into a digital signal in analog-digital conversion section 13. Arrival direction estimating section 15 estimates the number of mobile stations and directions thereof by processing the digital signal. Arrival direction tracking section 16 estimates a direction of a mobile station by sequential processing using an estimated result in arrival direction estimating section 15. Beam forming means 17 forms an antenna radiation beam to a direction of the estimated result in arrival direction tracking section 16.
