Title: Reduced complexity channel estimation in ofdm systems
Inventor: SVENSSON JIM
IPC: H04L27/26
Filed: 2006-04-07
Abstract: A channel response estimate is generated from a received signal that comprises two or more different pilot carriers in an Orthogonal Frequency Division Multiplexing (OFDM) communications system. This involves, for each of the carriers, determining a rotation amount that is at least in part a function of a frequency separation between two adjacent carriers, a delay spread of the channel, and a position of the carrier relative to other carriers within the received signal. The received signal is processed with a Fast Fourier Transform, thereby generating a processed signal. Prior to performing frequency interpolation as part of a channel estimation process, the processed signal is rotated by the rotation amount. The channel response is estimated by performing the channel estimation process at least in part on the rotated processed signal.
