| Abstract | Over the last few years Power Line Communication has gained importance for high speed data communication. One of the major concerns in PLC is noise and high data rate, several schemes have been adopted to minimize noise over PLCs and improve data rate. One of the promising approach is the use of Multi Band (MB) – Orthogonal Frequency Division Multiplexing (OFDM) Ultra Wide Band (UWB) to achieve date rates over 200 Mbps. One of the approaches is to integrate MBOFDM UWB with Digital Down Converter (DDC) for power line communication. In this work, MBOFDM UWB system is integrated with DDC on the transmitter and DUC is integrated at the receiver to achieve higher data rate. The integrated system modeled using Matlab and Simulink achieves BER of10 -3 and THD of 1.2. Rate 2/3 Convolutional encoder, scrambler, bit interleave, GMSK modulator and IFFT have been used generate MBOFDM, time-frequency kernel with frequency translation achieves UWB. DDC consisting of CIC and CFIR are used to downlink the UWB signal as compatible with PLC. |
