<p>This invention relates to Direct Sequence Code Division Mult-Access (DS-CDMA). The transmitter (104B) comprising a bit pattern decoder (304) including a first output (304A) for outputting a DS-CDMA code to a pulse shaper (206), and a second output (304B) that is coupled to a control input (312A) of amplifier (312). The bit pattern decoder functions to output a DS-CDMA code in response to a first set of bits that have a first value e.g., one, and serves to output a control signal to amplifier (312) to cause the amplifier (312) to cease output in response to a second set of bits that have a second value e.g., zero. Thus the transmitter (104B) is capable of performing DS-CDMA on/off signaling by ceasing output of the amplifier (312).</p> |
