High Integrity Carrier Phase Navigation for Future LAAS Using Multiple Civilian GPS Signals
High Integrity Carrier Phase Navigation LAAS Multiple Civilian GPS Signals
2015/6/29
In near future, there will be two more civilian GPS signals,at 1227.60 MHz and 1176.45 MHz, in addition to thepresent one at 1575.42 MHz. Of many possible benefits from the three civilian signal...
Analysis of Carrier Phase and Group Delay Biases Introduced by CRPA Hardware
Carrier Phase Group Delay Biases Introduced CRPA Hardware
2015/6/26
The benefits afforded by Controlled Reception Pattern Antennas (CRPAs) in multipath and interference mitigation are well documented, and they find use in many applications today. As such, CRPAs are be...
Wiener's Loop Filter for PLL-Based Carrier Recovery of OQPSK and MSK-Type Modulations
Wiener's Loop Filter PLL-Based Carrier Recovery OQPSK MSK-Type Modulations
2009/9/4
This letter considers carrier recovery for offset quadrature phase shift keying (OQPSK) and minimum shift keying-type (MSK-type) modulations based on phase-lock loop (PLL). The concern of the letter i...
Optimal Filtering in Pilot-Aided Carrier Recovery
Optimal Filtering Pilot-Aided Carrier Recovery
2009/9/4
The paper deals with carrier recovery based on pilot symbols in single-carrier systems. Wiener's method is used to determine the optimal unconstrained filter in estimation of phase noise assuming that...
