Advanced transceiver schemes for next generation high rate telemetry (original) (raw)

Abstract

We investigate the problem of increasing the spectral efficiency of current high rate telemetry systems in two different scenarios, which exploit one and two channels, respectively. We will analyze several techniques aimed at improving different stages of the transceiver scheme. We will optimize the transmission parameters and apply advanced receiver architectures, able to take into account part of the channel memory and of the interchannel interference. We will propose a new signal predistortion algorithm, which has very good performance in both considered scenarios, and we will show that, by combining the presented techniques, significant gains are possible over the current configuration. The whole analysis is aimed at providing information theoretical bounds to the achievable transmission rates.
