N2  - This work proposes a novel signalling method for
Narrowband Internet of Things (NB-IoT) mobile system where a
quadrupled data rate can be achieved by combining two orthogonal techniques; the frequency orthogonal Fast-Orthogonal Frequency Division Multiplexing (Fast-OFDM) scheme coupled with
the time orthogonal Hilbert transform (HT) pair. In this paper,
the orthogonality features of one dimension in Fast-OFDM and of
the HT pair are explored. The newly designed system structure
is presented where the HT pulse pair is generated by square
root raised cosine (SRRC) filter with a matched configuration
at the receiver. System performance is investigated in terms of
bit error rate (BER), effective data rate and spectral efficiency.
Simulation results show that the HT-Fast-OFDM system provides
4 times the data rate relative to an OFDM system employing the
same modulation scheme and occupying the same bandwidth.
Furthermore, the proposed system has compelling advantages
over 16-QAM OFDM for it achieves a better BER performance
at the same spectral efficiency
