Abstract
An apparatus and method to feedforward non-quantized precoding weights in an OFDM communication system includes a first step () of sending feedback information from a subscriber station (SS) to a base station (BS). A next step () includes deriving non-quantized weight information from the feedback information. A next step () includes transmitting symbols carrying the non-quantized weight information and non-precoded pilot symbols by the BS. A next step () includes receiving the information and symbols by the SS. A next step () includes estimating the non-quantized weights from the symbols carrying the non-quantized weight information and the non-precoded pilot symbols by the SS. A next step () includes decoding data from the BS by the SS using the estimated non-quantized weight information.
