摘要: A direct sequence spread spectrum receiver samples an incoming signal and translates the to IF signal. The is sampled ans stored in memory (192, 194). In one embodiment, consists of two banks which alternately receive sample segments. During a write period banks, other bank supplies its output processor (70). This continues ping-pong manner. another single filled read as necessary, ignoring until has completed processing available at memory. Such useful global positioning satellite (GPS) where contains several transmissions encoded with CDMA encoding.
