Multi-level modulation is useful for Efficient use of frequency band to achieve the high-speed communications on small satellites. In addition, low power consumption amplifier is needed for small satellites to reduce a load on transmitter. However, multi-level symbols be distorted by nonlinearlity of amplifier.
To achieve high-speed communications using X-band on small satellites, determination of optimum pre-distortion methods is essential.
We measured the low power consumption amplifier for evaluate a distortion of output symbols. As a results, the amplifier can be assumed that a memory-less amplifier at a small Input-Back-Off.
And then, we introduced a index K for get a relationship between IBO and mean power. the results shows that optimum pre-distortion method can be determined by the characteristic of K at selected IBO. |
