Optimizing Coded 16-apsk for Aeronautical Telemetry
نویسندگان
چکیده
This paper investigates the application of 16-APSK modulation to aeronautical mobile telemetry. The peak-to-average power ratio vs. code rate tradeoff is mapped to an optimization problem involving spectral efficiency and the constellation parameters. The optimization results produce a theoretically optimum solution that is 3.95 times more spectrally efficient as uncoded SOQPSKTG. When implementation losses and the available IRIG 106 LDPC code rates are factored in, the advantage drops to 3.20 times the spectral efficiency of SOQPSK-TG.

In this paper, with the aid of mutual information and generalized mutual information (GMI) capacity analyses, it is shown that the geometrically shaped APSK that mimics an optimal Gaussian distribution with equiprobable signaling together with the corresponding gray-mapping rules can approach the Shannon limit closer than conventional quadrature amplitude modulation (QAM) at certain range of FE...
متن کاملSpace - Time Coding for Aeronautical Telemetry : Part I — System Description
This paper described the design and implementation of a prototype transmitter and a prototype demodulator/decoder for space-time coded SOQPSK-TG for aeronautical telemetry. The design exercise showed that the space-time coding concept can be reduced to hardware. The laboratory bit error rate tests showed that the performance of the prototype demodulator in a 2-transmit/1-receive antenna configu...

A new class of 16-ary Amplitude Phase Shift Keying (APSK) coded modulations deemed double-ring PSK modulations best suited for (satellite) nonlinear channels is proposed. Constellation parameters optimization has been based on geometric and information-theoretic considerations. Furthermore, preand post-compensation techniques to reduce the nonlinearity impact have been examined. Digital timing ...
متن کاملAn approach to Integrated Spectrum Efficient Network Enhanced Telemetry (iSENET)
As the integrated Network Enhanced Telemetry (iNET) program moves forward in resolving systems engineering design and architecture definition, critical technology “gaps” and a migration path to realizing the integration of this technology are needed to insure a smooth transition from the current legacy point to point telemetry links to a network oriented telemetry system. Specifically, identifi...
