AB  - Power Line Communication (PLC) is a promising technique for information transmission using existing
power lines. However, the power line was not oriented for data transmission providinga rather harsh
environment. To overcome the difficulties, advanced modulation and channel coding schemes should be
employed. In this research a physical layer architecture that recommends the use of OFDM architecture
supporting peak data rates between 14 Mbps- 200 Mbps is modelled where OFDM multi-carrier transmission
technique could decrease the inter-symbol interference and frequency selective fading. Moreover Low Density
Parity Check code (LDPC) is employed to reduce the loss caused by various kinds of effects in the channel
especially the noise . The novel architecture in DWT with DUC/DDC is integrated with MB-OFDM and LDPC
for PLC. Further, the MB-OFDM integrated with DUC/DDC, consumes a total power of 42.66 mw for the
operating frequency in the range of 50-578 MHz. BER performances of MB-OFDM with DWT and LDPC have
been obtained based on the proposed model and have been demonstrated to achieve a higher BER for a given
noisy channel.
