A new class of codes was proposed recently for perfect multi-user interference (MUI) suppression in Code Division Multiple Access (CDMA) systems. These so called Lagrange-Vandermonde (LV) codes offer deterministic MUI elimination without channel estimation, and convert frequency selective channels into flat fading channels. In this work, we develop dual CDMA transceivers, naturally termed Vandermonde-Lagrange (VL), with the precoder-decoder roles interchanged, in order to improve system flexibility in the code assignment. We also derive and test non-redundant and redundant techniques for combating the residual flat fading.
