Spread spectrum PR-QMF transmultiplexer codes for CDMA communications
Orthogonal transmultiplexers have been successfully utilized for multiple access communications. They are of FDMA type in their most common version. The frequency selective PR-QMFs were used in transmultiplexers for CDMA communications reported in the literature. This conflicts with the fundamentals of CDMA theory. We introduce novel spread spectrum PR-QMF codes. It is shown that the spread spectrum PR-QMF codes with minimized auto- and cross-correlation properties drastically outperform the conventional Gold (1967) codes in CDMA communication scenarios considered.
