Abstract :
Multi-Carrier Modulation (MCM) is an effective technique in Morden communication system. Taking part in standard MCM performance, it uses Orthogonal Frequency Division Multiplexing (OFDM) which is very sensitive to the Carrier Frequency Offset (CFO). It leads to a distortion in subcarrier orthogonality and causes inter channel interference (ICI). In this paper, Wavelet Packet Transform is designed in support of the model of MCM as an alternative to the majority exiting Orthogonal Frequency Division Multiplexing (OFDM) performance. Its time-frequency representation and lower side lobes in transmitted signals reduce inter carrier interference (ICI), and inter symbol interference (ISI). Performance analysis such as BER and PAPR are investigated in support of such model. Result shows an efficient operational end.
