Advances in autarkic sensor nodes demands for higher performance and lower energy needs of wireless communication systems. Due to the fact, that they are both highly dependent on the modulation technique used, we investigate theoretically and experimentally the possibilities of new modulation techniques for very low power wireless transmission systems. Hereby we concentrate on chaos-based modulation techniques that look promising and have already proposed two new modulation schemes with distinct energy saving properties at high performance levels.
