Vorrichtung und Verfahren zum Senden eines quadraturamplitudenmodulierten Sendesignals

摘要

Device for sending a QAM-transmission signal comprising a trigger frequency f0, whereby the device is composed of one coding device (9) which codes data to form complex valued pairs (a, b) consisting of two data; a sensing device (14) for sensing complex valued pair signals with a first scanning frequency; a selector (36) which selects the carrier frequency f0; a memory (31) from which a phase increment delta phi associated to a carrier frequency can be read; a battery (25) which generates a phase signal phi depending on the phase increment delta phi reading, and at least one computation device (24) to produce the QAM-transmission signal by multiplying the complex value pairs with a phase rotation operator, whereby said complex valued pair is rotated at a phase angle phi corresponding to the phase signal.
