摘要
A system to decode a multirate CDMA signal. In one aspect the system includes a high rate detector to generate high rate outputs based upon decoding an input signal that includes high rate users and low rate users. The high rate outputs include actual high rate users and effective high rate users. A second stage applies a first linear transformation to the high rate outputs to generate second stage outputs. A third stage applies a second linear transformation to the second stage outputs to generate decoupled low rate user outputs and decoupled actual high rate user outputs.
