<p>A method and apparatus for creating non-interfering coded signals to be simultaneously transmitted over a common frequency in a wireless communication system, such as a CDMA system, at various data rates and without the use of orthogonal codes and/or orthogonal code generation techniques. The system provides cascaded arrangement of code modulations which each include a channel sequence combiner and selector. The channel sequence combiner receives an input signal and a repetitive maximum length channel sequence and combines these signals to produce a combined signal. The selector receives the input signal, the combined signal, and a repetitive strobe signal, and selects either the input signal or the combined signal to produce an encoded signal based upon a value of the repetitive strobe signal.</p> |
