The new G3RUH software modem for the DSP56002EVM

This paper presents the new design of the G3RUH software modem. This is a two level PAM modem that works at range of bit rates from 9600bps to 38400bps and admits different rates at transmission and reception. The major improvement of this new version is the synchronism algorithm and the structure of the reception filter. It provides a better performance of the modem. The software is aimed for ...

Energy-Efficient Assignment of User Equipment to Cooperative Base Stations

Future radio access networks (RANs) will activate and deactivate base stations (BSs) depending on the activity of users to conserve energy. Reducing the fraction of time a BS is enabled will reduce the energy consumption of the RAN. Using cooperative transmissions from BSs allows to reach user equipment (UE) that is not in range of any single BS. When some BSs cooperate, other BSs can be deacti...

An equalizer design technique for the PCM modem: a new modem for the digital public switched network

Modems designed for the public switched telephone network (PSTN) have conventionally been based on modeling assumptions which view the PSTN connection as an essentially analog medium. However, as the PSTN evolves toward all digital transport and switching, and particularly as major traffic sources, such as Internet service providers, increasingly have direct digital connections to the PSTN, it ...
