Abstract

Telecommunication networks have been identified to exhibit a substantial electrical power and energy demand. Therefore it is important to utilize power and energy efficient systems as building blocks for such networks. In wired access networks copper cables are used for highspeed data transmission. Important technical indicators for power and energy efficiency of transmission systems are transmit power and energy per bit. In this work it is investigated how transmit power and energy per bit in linearly equalized multilevel baseband cable transmission systems can be minimized by exploiting degrees of freedom in the transmission link design for given throughput and transmission quality. First, the constellation size is a degree of freedom: Its optimization leads to minimum values of transmit power and energy per bit depending on the interplay between throughput and band limitation of the cable. Second, the partitioning of the equalization to transmitter and receiver is a degree of freedom: Here, a uniform distribution of the linear equalizing function is found to be optimum in terms of minimum transmit power or energy per bit at a given transmission performance and quality. The results show that the optimization of constellation size and equalization partitioning leads to significant transmit power and energy-per-bit savings compared to conventional baseband cable transmission systems.
