Inhalt:
An application of time-domain equalization (TEQ) is discussed in the context of multi-carrier sensor networks. Designed as a DC power-line communication system (DC-PLC), the exemplary underwater sensor network of a sonar array uses a linear bus topology of the power distribution network for data transmission. Simulations show the advantages of a TEQ-enabled system, both using rate-maximizing or a classical shortening TEQ, in different bus configurations. As a result, the complexity of the corresponding modem implementations could be greatly reduced by using a shorter DFT, while still keeping the high data rate.
