Application of Time-Reversed Space-Time Block Code to Aeronautical Telemetry.

摘要

Generalized time-reversed space-time block codes (GTR-STBC) are introduced as a conceptual tool to examine the impact of unequal power allocation in aeronautical telemetry channels. Two transmitting antennas are employed to exploit partial channel state information. GTR-STBC are observed to perform the best trade-off between the signal-to-noise ratio and inter symbol interference. It is also observed that the optimum transmitter power profile for the measured channel is significantly different than that in the statistical channel model.
