SP5009E - Spread spectrum transmissions

Objectives

General objective:

The objective of this class is to present and analyze the principles of spread spectrum techniques for communications (DS-SS). The temporal and frequency-domain properties of the spreading sequences are presented. Then the structures of a transmitted and received DS-SS signal are analyzed. Finally, the reception techniques of the DS-SS signal are investigated, in particular the acquisition and tracking functions.

Detailed objectives:

Course structure :
- Presentation of temporal and frequency properties of spread codes and influence of code materialisation
- Presentation of structure ofsignal DS-SS transmitted
- Presentation of theoperation of corellation performed by a receiver DS-SS
- Presentation of techniques of reception of DS-SS signal, in particular techniqus of acquisition and a pursuit.

At the end of the cours a student :
- will know the principle of spread spectrum transmissions
- will be able to design a chain of reception DS-SS
- will understand techniques of typical processinf of signals using spread spectrum (acquisition, pursuit).
