VERFAHREN ZUR STÖRSIGNALUNTERDRÜCKUNG BEI DER ÜBERTRAGUNG DIGITALER SIGNALE

摘要

A method for the transmission of digital signals, particularly in the AM bands (broadcasting bands), with high-level modulation, preferably 32 APSK or 64 ASPK, being used for data blocks to be transmitted. At the receiving end, time-periodic measurements of a noise are carried out and noise signals determined therefrom are subtracted from received signals.
