Digital Pulse Interval Modulation (DPIM) is a pulse-interval modulation technique and a modified form of PPM which has been shown to be suitable for deployment in optical-wireless-communication systems.A spread spectrum digital pulse interval modulation (SSC-DPIM) communication strategy for power-line communication is investigated , where the DPIM symbols are encoded using a swept frequency carrier coupled to the power line and a preamble DPIM frame with a fixed interval is used to mitigate the data error propagation. The presence of the frequency swept carrier on the PL will represent the presence of a DPIM pulse, and the absence of the carrier will represent the spacing state of the SSC-DPIM frame. The theoretical analysis about the data transmission rate and the data block error rate are studied. The SSC-DPIM system is implemented by a single-chip micro-processor and has been applied successfully in a train fault information system based on power-line communications. The experiment results show that the SSC-DPIM system has an advantage over the most established power-line communication techniques in bit data error rate in the presence of a high signal attenuation and strong complicated noise.
