Global positioning system (GPS) receivers find growing applications in indoor and outdoor communication environments, including urban and rural areas. Interference and noise sources for GPS receivers may assume Gaussian or non-Gaussian distributions. The GPS receiver performance under Gaussian additive noise has been studied. Non-Gaussian noise may equally(More)
The performance of GPS delay lock loop (DLL) can be greatly compromised by multipath. This paper considers the effects of multipath on the GPS receiver. It evaluates the DLL performance in terms of the tracking error of the noncoherent early-minus-late power discriminator. We discuss the effect of precorrelation filter bandwidth on the autocorrelation(More)
Signal multipath in GPS leads to undesirable tracking errors and inaccurate ranging information. The extent of the tracking error in compromising the receiver performance depends on the multipath amplitude, delay, and phase relative to the direct path. The coherent discriminator and the noncoherent early-minus-late power discriminator offer different(More)
It can greatly improve the system performance by introducing cooperative communication into Cognitive Radio Networks (CRNs), but it has also increased the complexity of the CRNs. As is known to all, the average throughput of the CRNs will decrease as the number of relay nodes increases. In order to solve this problem, we used a selection amplify-and-forward(More)
Signal multipath leads to undesirable tracking errors and inaccurate ranging information for GPS receivers. The extent of the tracking error in compromising the receiver discriminator performance depends on the multipath amplitude, delay, and phase relative to the direct path. Compared with the rural area, the GPS receiver in the semi-enclosed area, such as(More)
