Satellite navigation system Signal quality directly influence on the performance of the satellite navigation system. An ensured coherence of the code phases of the carrier phases is not only the premise for pseudo-random code ranging and carrier phase ranging, but one of the main factors that influence the positioning accuracy of navigation signals. In this paper, aiming at the code-carrier phase...
A dual-polarization quadrature phase-shift key coherent receiver based on polymer planar lightwave circuit is presented. Polarization beam-splitter, optical 90° hybrids and photodiodes are hybridly integrated on one chip. Basic characteristics of the receiver are given.
The problem of transmitting a source across a parallel channel with random states only known at the decoder is considered. We focus on minimizing the average distortion. The general problem is unsolved. There are two commonly used architecture, namely source coding diversity and channel coding diversity, which exploit diversity through parallel channel coding or multiple description (MD) source coding...
We demonstrate a DPSK receiver with a 2×25 GHz photodiode array hybrid-integrated on polymer PLC via 45° mirrors. With a half-wave plate and micro-heaters, the polarization-dependent frequency-shift of the delay-line interferometer can be eliminated.
A novel dual-quadrature coherent receiver based on a polymer planar lightwave circuit is presented. The packaged receiver is successfully operated in 112 Gb/s DP-QPSK transmission experiments showing only 1.3 dB penalty compared to theory.
One of the main drawbacks of partial transmit sequences (PTS ) scheme is the requirement of side information (SI) for phase recovering at the receiver end, which reduces the frequency efficiency as well as transmitting performance. In this paper, a blind PTS using partial phase recovering scheme without SI is proposed for pilot-aided OFDM systems. The proposed scheme exploits the relationship between...
In this paper, within a group of cooperating agents the decision making of an individual agent depends on the actions of the other agents. In dynamic environments, these dependencies will change rapidly as a result of the continuously changing state. Via a context-specific decomposition of the problem into smaller sub-problems, coordination graphs offer scalable solutions to the problem of multi-agent...
In this paper, we have proposed a bandwidth efficient turbo trellis-coded modulation scheme for the non-coherent multiple-antenna Rayleigh fading channel, where the channel state information is not necessary both at the transmitter and the receiver. In this scheme, we merge the unitary space-time modulation as constellations with the turbo trellis-coded modulation, resulting in the turbo trellis-coded...
