Embodiment Construction

[0023] The methods and apparatus disclosed herein provide an operating system for adjusting the power of a code signal. The disclosed system provides the necessary gain adjustment scheme for the code signal. Gain adjustments are calculated using uploaded symbol tables, providing flexibility for on-orbit reconfiguration of waveforms.

[0024] The disclosed system accommodates code multiplexing by using a precomputed table (ie, symbol table) to adjust the gain on a code signal (eg, a Global Positioning System (GPS) signal). As mentioned earlier, coded signals use different codes modulated on a carrier signal to increase information throughput. Various code combining schemes utilizing code signals have been proposed, which are easily implemented using digital waveform generators (DWGs), which typically operate at a fixed optimized output back-off level regardless of the code set. In order to accommodate reconfigurations due to increasing or decreasing codes or enhancing relativ...

Abstract

The present invention relates to methods and systems for adjusting the power of a code signal. Systems, methods, and apparatus for power adjustment of code signals are disclosed. In one or more embodiments, the disclosed method for adjusting power of a code signal includes determining, by at least one processor, a code loss for transmission of the code signal by using a symbol table. The method further includes determining, by at least one processor, an amount of change in attenuation of at least one adjustable attenuator on at least one vehicle using the loss of code. Additionally, the method includes adjusting the attenuation of at least one adjustable attenuator by the amount of change in attenuation.

Description

technical field [0001] The present disclosure relates to power adjustment and, in particular, to adjustment of code signals. Background technique [0002] Coded signals (eg, Global Positioning System (GPS) signals) use different codes modulated on a carrier signal to increase information throughput. Various code combining schemes utilizing code signals have been proposed, which are easily implemented using digital waveform generators (DWGs), which typically operate at a fixed optimized output back-off level regardless of the code set. In order to accommodate the reconfiguration caused by adding or subtracting codes or enhancing the relative code power, the gain after DWG must be adjusted according to the redistribution of code power in DWG. Therefore, when there is a change in code power, the gain after DWG needs to be adjusted. [0003] Existing solutions use analog devices for waveform generation and are limited to a small set of preselected code configurations. Digital...
