For that bounds on the semi-analytic symbol-error rate (SER) expressions are derived and simulation studies are conducted. When practical implementations of MCSK and MPPM are considered it is shown that MCSK can provide about 2 dB performance gain over MPPM as it reduces the effects of multipath delays on the decision variables by randomizing locations of the transmit pulse.eninfo:eu-repo/semantics/openAccessM-ary code shift keying (MCSK)Impulse radios (IRs)Ultra wideband (UWB) communicationsRandomized locations of the transmit pulseArticle3285329197WOS:00025967400000310.1109/TWC.2008.0703142-s2.0-52349085761Q1Q1
