the transmission frame includes 16 groups of 24 symbols each with each of the 16 groups being weighted by different weights for transmission the process begins at step 200 at step 202 the channel response of channels h 0 t and h 1 t are estimated in matched filter estimator 126 by applying matched filters on the pilot channels pilot 0 and aux pilot 1 the channel estimates are done once per symbol the matched filtering operation for channel estimates to perform the estimation is well known in the art matched filter estimator 126 then sends the estimated channel responses h 0 t and h 1 t to weight encoder 128 next at step 204 weight encoder 128 calculates the weights w 0 t and w 1 t for each channel h 0 t and h 1 t respectively from the estimated channel responses in the embodiment w 0 t and w 1 t are amplitude and phase information the weights are calculated 16 times once every group of symbols for each frame the weights are sent to the base station at the same rate once per group the weights for one frame may not all be calculated before the frame is transmitted the.
