The future of wireless communications, with 5G on the horizon, stands on higher data rates, spectral efficiency and flexibility requirements as the evolution and expansion of mobile communications brought the need to transmit efficiently over hostile channel conditions at changing rates. New modulation techniques are therefore needed in alternative to OFDM, such as the recent proposed Time Interleaved Block Windowed Burst OFDM (TIBWB-OFDM) technique.

However, backward combability and compliance with current RF LTE frame structure would be desirable.

The purpose of this work is, therefore, to integrate the process of constructing the TIBWB-OFDM symbols into the structure of an LTE signal. To do this, we must first ensure the greater confinement in the spectrum obtained by converting the OFDM symbols to block winded burst (BWB)-OFDM, in which the OFDM symbols are simultaneously cyclically extended and windowed through a Nyquist window. Then, it is generated the TIBWB-OFDM sysmbol by performing interleaving on the time-samples of each BWB-OFDM block, which creates a kind of diversity effect at the frequency domain, granting a much better resilience against deep inband deep-fades. Note that, due to the structure defined in the LTE signals, there are certain predefined signals, which have varied objectives such as temporal and spectral synchronization, but also cell identification, among others. These signals are transmitted periodically in pre-defined sub-carriers of LTE frame structure. Therefore, in order to maintain the structure of the LTE signals and taking into account that after constructing the TIBWB-OFDM symbols, they appear with a greater number of samples than the original OFDM symbols due to the application of the mentioned operations, it is necessary to take some measures.

Thus, this work aims to identify these measures with the objective of integrating the operation of a TIBWB-OFDM transceiver with the respective structure of an LTE signal.
