Abstract :
Conventional code acquisition techniques don´t exploit the entire available information for decision making but only use a part of it. A maximum a posteriori probability (MAP) code acquisition scheme is proposed which efficiently utilizes all the available information by exploiting statistical properties of spreading codes. Computer simulations show significant performance improvements over conventional schemes
