WebSummary. A spread-spectrum signal can be created by multiplying the existing baseband signal by a spreading sequence, also known as a PN code. The original signal is recovered by multiplying the spread-spectrum signal by the same PN code. A spread-spectrum signal has lower peak power, equal total power, and wider bandwidth.
