Narrowband channel model for aeronautical telemetry
A narrowband channel model for multipath fading in aeronautical telemetry applications is described. This channel is composed of a line-of-sight signal, a specular reflection whose strength is 20% to 80% that of the line-of-sight signal, and a diffuse multipath component whose power is 10 to 20 dB less than that of the line-of-sight signal. Thus the channel is close to additive white Gaussian n...
متن کاملLong Range Channel Prediction in Aeronautical Telemetry
Long range prediction exploits the principal that the memory span of a predictive filter increases when it samples the input signal at a lower rate. Within the context of a communication system that employs adaptive modulation and coding communication, this implies that by measuring the channel at a rate that is minimally twice the highest Doppler frequency rather than twice the data rate (the ...
متن کاملChannel Equalization and Spatial Diversity for Aeronautical Telemetry Applications
This work explores aeronautical telemetry communication performance with the SOQPSKTG ARTM waveforms when frequency-selective multipath corrupts received information symbols. A multi-antenna equalization scheme is presented where each antenna’s unique multipath channel is equalized using a pilot-aided optimal linear minimum mean-square error filter. Following independent channel equalization, a...
متن کاملSystem Design For FEC In Aeronautical Telemetry
This paper contains a description of two types of forward error correction (FEC) codes for shaped offset quadrature phase shift keying, telemetry group version (SOQPSK-TG). The FEC codes are a low-density parity check (LDPC) code and a serially concatenated convolutional code (SCCC). The contributions of this paper are on the system-design level. One major contribution is to design a SCCC code ...
متن کاملOptimizing Coded 16-apsk for Aeronautical Telemetry
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 implemen...
