In Orthogonal Frequency Division Multiplexing (OFDM), Fourier Transform (FT) is used as a modulation technique. To avoid Inter-symbol Interference (ISI) in OFDM by a time dispersive channel, a Cycle Prefix (CP) is used which also reduces its spectral efficiency. Discrete Wavelet Packet Transform (DWPT) as a modulation scheme has been proposed for wireless communication. In this paper, DWPT based OFDM...
In this paper, we suppose a new system called MIMO-OCWDM system which combines MIMO with orthogonal complex wavelet division multiplexing (OCWDM). The results are simulated using V-BLAST architecture with different transmit and receive antennas; their performance are analyzed in terms of bit error rate (BER). We evaluate that the performance of MIMO-OCWDM system is much better than that of MIMO-OFDM...
