Abstract

In this paper we present an approach to reduce the receiver dynamic range in wireline channels, by decreasing the peak to average power ratio (PAPR) at the analog to digital converter (ADC) input. The suggested approach uses precoding at the transmitter which creates a maximal entropy distribution, such that symbol sequences that will result to high peak power values at the receiver are avoided. The overall gain of such shaped system is measured compared to a non-shaped system. For 8-PAM system over typical wireline channel, an overall theoretical gain of 3 dB is achievable with data rate of 2.5 biysymbol. The suggested approach can be used to improve any wireline communication link, limited by the ADC saturation point.
