ABSTRACT:
A method and apparatus are provided for adaptively allocating pilots in a pilot-aided channel estimation system. A multipath delay is measured between a base station (BS) and a mobile station (MS). A distribution density of pilots of a signal to be transmitted between the BS and the MS is controlled. When the multipath delay is large, the pilot distribution density is relatively raised. However, when the multipath delay is small, the pilot distribution density is relatively lowered. The pilot distribution density is adaptively controlled according to the multipath delay, such that resources are effectively utilized and throughput is improved.
