1. A code division multiple access user equipment for use in receiving a plurality of data signals received over a shared spectrum, each received data signal experiencing a similar channel response, the user equipment comprising: means for receiving a combined signal of the received data signals over the shared spectrum; means for sampling the combined signal at a multiple of a chip rate of the combined signal; means for estimating a channel response for the combined signal at the multiple of the chip rate; means for determining a column of a channel correlation matrix using the estimated channel response; means for determining a spread data vector using the determined column, the estimated channel response, the received combined signal and a fourier transform; and means for estimating data of the data signals using the spread data vector.
