Abstract:

Power line Communication (PLC) system offers cheaper mode of signal communication facilities. However, in fast Fourier transform (FFT) based OFDM system, a cyclic prefix (CP) of the same length as the channel impulse response needs to be added after each symbol to avoid inter symbol and inter carrier interference. This paper investigates the benefits of a filter bank based Wavelet Transform OFDM (WTOFDM) approach that doesn't need the cyclic prefix and hence has higher throughput. Different types of wavelets based OFDM links are compared by simulation and the bi-orthogonal wavelet is found to be the best for PLC applications.
