As the Compass satellite system is under construction, various applications are emerging. Multipath mitigation is still a critical problem that must be resolved, especially short delay multipath. Research on multipath mitigation is reported and a multipath limiting antenna array including the algorithm is discussed. The carrier phase data of the receiver are subjected to forward–backward spatial smoothing...
The binary offset carrier (BOC) modulation offers improved performance and the opportunity for spectrum sharing while retaining implementation simplicity. However its drawback is the ambiguity of the autocorrelation function (ACF), which induces a complexity in the acquisition process, and a risk of biased measures while tracking. The traditional techniques for the classic BPSK modulated signal have...
This paper analyzes the sensitivity of delay lock loop (DLL) of GPS receiver to thermal noise, interference, and multipath. Analytical expressions apply for various correlator spacings and front end bandwidths. Remarkable performance advantages over the conventional one chip correlator spacing is shown
This paper structures a novelty sampling and reconstruction framework for band limited signal. The conditions under which signal can be exactly reconstructed from its non-uniform samples, more general than the ones presented in [1], are developed. All this enriches and deepens the classical sampling theory.
In [1] [2], a blind recursive least squares (BRLS) adaptive algorithm for interference suppression in CDMA systems is derived. However, this algorithm and its performance analysis are reached in a heavy and complicated way. This paper presents a new and simple algorithm which has the same performance as the foregone BRLS algorithm.
