Short burst direct acquisition direct sequence spread spectrum receiver

摘要

This invention discloses the architecture and circuit details of a Direct Sequence (DS) spread spectrum baseband receiver. This baseband receiver applies to short data burst applications that are required to rapidly acquire before continuing with reliable data demodulation. The design is also suited for DS receivers that use antenna diversity by serially processing each individual antenna input. The emphasis of the implimentation techniques is to high performance while minimizing hardware size and cost.
