High-speed broadband power line communications (BB-PLC) have become a good option  for all residential subscribers. Today regulations imply the use of multi-carrier (MC) systems, like orthogonal frequency-division multiplexing (OFDM) or, as an alternative, the use of single-carrier (SC) technologies as main modulation scheme. In this work,  it is proposed a complementary sequences (CS) based frequency domain equalization (FDE) scheme  for use in SC systems, and it is compared with  zero forcing (ZF) and minimum mean-square error (MMSE) techniques. Finally, the present proposal and previously proposed OFDM PLC scheme (Part 1)  will be discussed and compared  through realistic simulations carried out by using different Middleton Class A (MCA)  impulse  noise model  and by using two PLC channel models available in the literature.
