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 ...

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 ...
