Seguir leyendo arrow_right_altThe seminar will cover the current status of the standardization in 3GPP of the new 5G radio interface (NR) and core network (NGC), including the steps undertaken for the acceleration process recently approved, that will allow for early implementations by the end of 2018.
Seguir leyendo arrow_right_altA new two-dimensional modulation technique called Orthogonal Time Frequency Space (OTFS) modulation designed in the delay-Doppler domain is introduced as a waveform ideally suited to new 5G use cases. Through this design, which exploits full diversity over time and frequency, OTFS coupled with equalization converts the fading, time-varying wireless channel experienced by modulated signals such as OFDM into a time-independent channel with a complex channel gain that is roughly constant for all symbols. Thus, transmitter adaptation is not needed. This extraction of the full channel diversity allows OTFS to greatly simplify system operation and significantly improves performance, particularly in systems with high Doppler, short packets, and large antenna arrays. Simulation results indicate at least several dB of block error rate performance improvement for OTFS over OFDM in all of these settings which translates to significant spectral efficiency improvements.
5G is on the horizon. In this talk, I will take a service-oriented perspective of 5G aimed at supporting a wide range of services, differing significantly in their service requirements and device types (including machine-type devices).
