The design of non-destructive testing systems for fault detection in long and not accessible pipelines is an actual task in the industrial and civil environment. At this purpose the diagnosis based on the propagation of guided ultrasonic waves along the pipes offers an attractive solution for the fault identification and classification.

In this work a procedure for the optimization of the bit loading in a PLC system implementing OFDM modulation is presented. The optimization strategy aims to find the best compromise between Signal Power, Bit Rate (BR), Bit Error Rate (BER) and Peak-to-Average Power Ratio (PAPR). The problem is approached from two points of view. First, the conflicting(More)
