A New Long Term Evolution LTE 3GPP Transceiver Based OFDM Multiwavelet Signals

الملخص

In this paper, an overview of the Long Term Evolution (LTE) is presented. LTE is the development of the Universal Mobile Telecommunications System (UMTS). It allows mobile users to access the Internet through their devices (mobile telephones, laptops…). LTE intends to deliver high-speed data and multimedia services to the next generation. The main contribution of this work is to propose a new LTE 3GPP Long Term Evolution Physical Layer Transceiver scheme based on Orthogonal Frequency-Division Multiplexing OFDM, Discrete Multiwavelet Transform (DMWT). The proposed Transceiver scheme has been designed and tested to investigate whether it achieves its goal. 6 SUI-channel types have been used. The simulation by Matlab approved the proposed design which achieved much lower bit error rates (BER), increased signal-to-noise power ratio (SNR), robustness for multipath channels and does not require cyclically prefixed guard interval, and has higher spectral efficiency than transceiver based OFDM on Discrete Wavelet Transform (DWT) and Fast Fourier transform (FFT) also can be used as an alternative conventional transceiver used in present time.
