MIMO Spread Spectrum

open access: yes, 2022
[EN] This thesis deals with the analysis of channel estimation in MIMO (Multiple-Input MultipleOutput) systems with a Frequency Selective Rayleigh Fading Channel, under the condition of having employed Direct Sequence Spread Spectrum techniques and have maintained the orthogonality of the codes by using Zadoff-Chu sequences as well as employing Cyclic ...

The MIMO-OTFS Technique in the Next 6G Communications

open access: yesEngineering Access
The orthogonal time-frequency space (OTFS) technique is a promising method of waveform modulation that encodes data in the delay-doppler (DD) domain. OTFS distinguishes itself from conventional multiplexing methods by employing two-dimensional modulation
