  • Publication number: 20190296518
    Abstract: In a drive unit according to an embodiment of the present disclosure, in each of a plurality of current pulses, a rising crest value is the largest, and after the rising, the crest value is damped. Further, a rising crest value of a pulse of an n+1-th wave is smaller than a rising crest value of a pulse of an n-th wave. Furthermore, rising crest values of the current pulses of a second wave and waves after the second wave are determined by a mathematical function expressed as an electric potential change caused by ON-OFF of an RC time constant circuit that is single-end grounded. Moreover, in the mathematical function, a time constant at an OFF time is larger than a time constant at an ON time.

  • Publication number: 20190181910
    Abstract: In a case that a large number of terminal apparatuses that are accommodated by contention-based radio communication technologies share a frequency resource, the number of data signals of the terminal apparatus that are non-orthogonally multiplexed in the spatial domain increases. If terminal apparatuses, of which the number exceeds the number of receive antennas or the spreading factor transmit uplink data at the same time, it is tantamount to a presence of terminal apparatuses using the same spreading code, and inter-user interference becomes a problem.

  • Publication number: 20190165826
    Abstract: In a case that a large number of terminal apparatuses accommodated in a contention based radio communication technology share a frequency resource, the number of data signals of the terminal apparatuses which are non-orthogonally multiplexed in the spatial domain increases. Therefore, in a case that the number of non-orthogonally multiplexed data signals of the terminals is considerably large, residual interference after removing interference in the reception processing degrades transmission performance.
