BER Analysis of Power Rotational Interleaver on OFDM-IDMA System Over Powerline

Power line communication (PLC) is a technology of transferring data over power lines. As the power lines were not designed to carry communication signals, noise in the form of impulses and fading corrupt the signals. Researchers have proposed various techniques to make communication over power lines feasible such as interleave division multiple access (IDMA), code division multiple access (CDMA), and orthogonal frequency division multiplexing (OFDM). The most promising results have been obtained by employing a combination OFDM-IDMA scheme which tends to resolve both the issues caused due to impulse noise and fading. But the key factor in the performance is based on the type of interleaver used in the system. In literature, many interleavers have been proposed such as random, prime, power, tree-based, and power rotational out of which the performance of power rotational interleaver has not been implemented in OFDM-IDMA over PLC. The paper aims to bring out the key aspects of power rotational interleaver and analyze the performance in terms of bit error rate by performing simulations in MATLAB and also present a comparative study with the other interleavers.
