METHOD AND DEVICE FOR DATA TRANSMISSION WITH OPTIMISED TRANSMITTED SIGNALS

摘要

In conventional data transmission from transmitting station to receiving station, knowledge of the channel impulse response of the channels between the transmitting and receiving stations is not utilised on creating the transmitted signals. Said knowledge is available to the transmitter, however, in, for example, transmission systems which work in time duplex. The aim of the invention is to make use of the information of the channel impulse responses on the transmitter side. Said aim is achieved, whereby requirements are set for the received signal, which are met by a suitable configuration of the transmitted signal, using the knowledge of the channel impulse response. The requirements on the received signal comprise, for example, that the information can be gleaned from said signals at the receiver in a particularly facile manner. The transmitted signals can be configured such that, not only the requirements of the received signals are met, but also that certain additional criteria may be met, for example, the criterium of minimal crest factor. The range of application is preferably cellular or non-cellular data transmission systems with fixed or mobile stations. Furthermore the said invention may be used for hard-wired data transmission.
