| Summary: | - OFDM multicarrier communication and wavelet-packet based both in frequency-domain and in time-domain but their channel occurs. OFDM multicarrier communication has densely communication is the principle of transmitting data by divid discrimination at the receiving end is guaranteed due to the ensured even though sub-carrier spectra may overlap. OFDM given, and ing the stream into several parallel bit streams, each of models of the two forms are proposed, analytical multicarrier communication are presented. Multicarrier multicarrier communication employs wavelet-packets to be the of individual sub-carriers. Wavelet-packet based orthogonality if rapid time-variations frequency error of the orthogonality of the wavelets-packet functions. The system probabilities of error with frequency dispersion and AWGN are pulse-shaping filters for sub-channels. The spectra overlap robust against time domain impulse interference due to long spaced sub-carriers and overlapping spectra. Its time-domain steep bandpass filters that completely separate the spectrum streams to modulate several carriers. It tends to be more symbol time. However, the sub-carriers may lose their mutual The multicarrier communication is studied. Two special forms the results of simulation are presented. waveforms are chosen such that mutual orthogonality is which has a much lower bit rate, and by using these sub- with raised cosine filter multicarrier communication use |
