Abstract
An apparatus and method for regulating arrangement of pilot subcarriers to improve a channel estimation throughput in a wireless communication system using an Orthogonal Frequency Division Multiplexing (OFDM) scheme are provided. The apparatus includes a pilot pattern manager for providing control such that pilots are non-uniformly generated according to a distance of a preamble in order to provide a constant link throughput of the frame when the downlink frame is generated.
