Abstract
In a synchronous code division multiple access (SCDMA) system, a set of substantially orthogonal code words is selected such that each code word in the set of substantially orthogonal code words is minimally correlated with a channel characteristic such as noise. When a station transmits a data signal, it multiplies the data signal by its assigned code word in order to produce a spread data signal. The spread data signal is transmitted over the channel of the SCDMA system.
