What is Understanding Spread Spectrum Techniques about?
Spread spectrum techniques spread modulated signals across a wider bandwidth than the minimum required to transmit the information. This is done by combining the input signal with a spreading code or sequence. The spread signal improves immunity to noise and interference and allows multiple users to share the same frequency band. At the receiver, the original signal is recovered by despreading the signal with a synchronized code. Direct sequence spread spectrum spreads each bit into multiple bits by XORing
