Apparatus and method for generating a transmit sequence, and apparatus and method for determining an information word from a received transmit sequence (original) (raw)

1999

Abstract

The aim of the invention is to reduce the out-of-band radiation in a distortion-free manner. A plurality of candidate transmission sequences is produced (10) from an information word. One of the candidate transmission sequences which meets a predetermined criterion is then selected (30). A different tag is added (12) to the information word respectively for producing the different candidate transmission sequences. The information word, together with the added tag, is subsequently processed by means of an invertable feedback combination algorithm (16) for obtaining a combined information word, wherein the information units are combined to each other and/or the added tag in such a way that the combined information word is clearly identified by the tag. The combined information word is fed to an algorithm in the receiver. Said algorithm is inverse in relation to the feedback combination algorithm and is automatically controlled by the tag for reproducing the information word. The infor...
