Multi-User MOCZ for Mobile Machine Type Communications
Abstract—We introduce multiple access schemes for a novel
non-coherent single-carrier (SC) modulation, called modulation
on conjugate-reciprocal zeros (MOCZ), to enable a high-spectral
efficient and mobile machine-type-communication for up- and
downlink transmissions. The modulation can be used for a
time-division and frequency-division multiple access (FDMA).
To utilize FDMA we will adapt SC-FDMA techniques and
demonstrate that a time-overlay of multiple users (MU) can
significantly reduce the peak-to-average-ratio (PAPR) in the
downlink. Furthermore, we compare the MU-MOCZ schemes
to standard modulations in narrow-band-Internet-of-things (NBIoT)
scenarios with smallest transport block size in the LTE
bands. To adapt the standard numerology of the transport
channel we introduced soft decoding for higher order MOCZ
designs. We demonstrate that our proposed schemes outperforms
the standardized scheme in highly mobile and frequency
Further, to build long lasting relation, we are forwarding you our company profile for your reference.
