In this dissertation is discussed and analyzed the performance of pilot-assisted channel estimation techniques for OFDM (Orthogonal Frequency Division Multiplexing) modulation that is applied to data transmission through PLC (power line communications) channels. The PLC channels are modeled as linear and time-invariant (LIT), linear and time variant (LTV), and linear and cyclic time-variant (LCTV) ones when the additive impulsive gaussian noise (AIGN) is considered. Performance analysis obtained with adaptive and nonadaptive channel estimation techniques together with channel equalization and pilot signal allocation ones are provided. The results based upon performance simulation offer interesting directions to improve pilot-assisted channel...
