In this paper, an M-ary Code Selected Direct Sequence Bipolar Pulse Amplitude Modulation (MCSDS-BPAM) ultra wideband system is introduced and the code selection criteria of this system is investigated. The particular DS code sequence used in MCSDS-MPAM scheme is selected by the log2M/2 bits from the DS code set, which offers the system higher data rate without increasing the system bandwidth or changing the pulse shape compared to other M-ary modulation schemes. The system performance can be varied by the selection of DS code set from the common DS code set without any extra expense.
