Low-complexity quasi-synchronous CDMA systems are derived for eliminating MUI completely in the presence of unknown and even rapidly varying multipath. They rely on judiciously designed precomputable user codes and offer a generalization of orthogonal frequency division multiplexing, especially valuable when carrier frequency errors and Doppler effects are present.
