3. Motivation
Direct Sequence Spread Spectrum is one of the most widely used algorithm in communication applications.
The implementation of the DSS algorithm lends itself to optimization at different levels.
Speeding up the algorithm gives us more opportunity to increase the efficiency in tracking part of the algorithm to reduce multi-path fading effect in CDMA systems
It also gives us faster acquisition time for initial synchronization of the data.
