Abstract
Wavelets have been applied in wireless communication systems in source and channel coding and transceivers design. This article proposes a new multi-carrier modulation approach to use Haar and Daubechies (Db2) wavelet-based stationary wavelet transform (SWT) in place of FFT because of no cyclic prefix, high spectral efficiency, less bandwidth usage, and its performance comparison of conventional transforms techniques such as FFT, DWT with SWT in an OFDM transceiver for Long term Evolution (LTE) in Stanford University Interim (SUI) channel models with zero-forcing equalization technique in the receiver section. The proposed system was tested with different modulation constellations such as PSK, QPSK, 64, and 128-QAM with 3GPP specifications for two users with user equipment data, ETU parameters (Extended typical urban) ETU-70 Hz, and calculated the BER. In SUI channels, 3dB of gain is improved in terms of energy per bit to noise ratio
