CHANNEL ESTIMATION FOR A CONTROL CHANNEL IN AN OFDM SYSTEM
摘要
A method of channel estimation for a control channel in an OFDM system of the present invention includes the steps of: performing weighted averaging over time of input LS estimates of a plurality of channel condition matrices; performing frequency domain averaging on the input LS estimates; performing channel estimates on multiple subcarriers of pilot OFDM symbols from the frequency domain averaged input LS estimates; and performing channel estimates on multiple subcarriers of OFDM symbols in the control channel from the channel estimates on the subcarriers of pilot OFDM symbols.
