DIGITAL SIGNAL RECEPTION SYSTEM

摘要

The error rate performance of a digital radio system which is deteriorated due to inband interference components can be effectively improved by adopting the present digital signal reception technique. A narrow band band-elimination filter removes the interference, and after the digital signal is regenerated, the spectrum, which is removed by said band-elimination filter, is recovered from the regenerated digital signal. The recovered digital signal is added to the original one, and is applied to the regenerator. Thus, even if there is an interference component in the same pass-band as the digital signal, it can be removed and the digital signal re-obtained without the interference component.
