Method for efficient sampling in a correlator |
摘要 |
A direct sequence spread spectrum receiver samples an incoming signal at a low non-integer sample rate relative to the input data rate. The sample rate is an integer rate relative to a defined data segment. As multiple segments are sampled, the non-integer sample rate causes bit/chip samples to process relative to the incoming data. Because the sample rate is an integer relative to a data segment, the samples are substantially stationary relative to each segment. Such a method is useful in global positioning satellite (GPS) signal processing wherein the time to first fix is minimized by having to correlate fewer sample points in the acquisition process. |
