ABSTRACT:
A base station constructs CDMA channels, each defined by a respective spreading sequence which modulates information bits to be transmitted for forming a respective channel signal. The different channel signals are combined, and then modulated on a carrier frequency, so as to produce a phase shift keyed radio signal which is transmitted towards mobile stations. Each spreading sequence has only one real component. For producing the radio signal, a relative phase shift is applied between different channel signals.
