Analysis of linear multiuser detection for DS CDMA
Spread spectrum techniques originated in answer to the needs of military communications. They are based on signaling schemes which greatly expand the transmitted spectrum relative to the data rate. A transmission technique in which a pseudorandom code, independent of the data, is employed as a modulation wave form to spread the signal energy over a band width much greater than the information signal band width is called SSM. The modulated output signals occupy a much greater band width than the signals base band information band width. To qualify has a spread spectrum signal, two criteria should be met.
