A 400-MHz phase-mux-based O-QPSK transmitter (TX) for medical imaging applications is presented in this paper. The modulation signal is generated by selecting one of the four quadrature phases to the ...

This paper proposes a novel introduction of the multidimensional multilevel block coded modulation (ML-BCM) to the quasi-synchronous CDMA (QS-CDMA) system, where the code delay uncertainty at the base ...
