Abstract
A channel spreading device for a base station in a CDMA communication system is described. The device comprises a spreading code generator for generating a real-component spreading code and an imaginary-component spreading code corresponding to a designated channel spreading code index; a circuit receiving a mode control signal, for disabling generation of the imaginary-component spreading code when the received mode control signal indicates a BPSK (Binary Phase Shift Keying) modulation mode; and a complex multiplier receiving a channel signal, for complex multiplying the received channel signal by the spreading codes to spread the channel signal.
