| Abstract: In this paper a new pulse shaping method in MSK-type signaling is proposed. The proposed pulse shaping method is based on the Walsh functions, and is used to design the optimum pulse shapes in MSK-type signaling. Simulation results show that the proposed pulse shaping method attains improvement in spectral efficiency (i.e., bps/Hz) over MSK, for the same channel bandwidth. The fractional out-of-band power is used to compare the behavior of the system under the new proposed technique. As well, error rate performance in such system is used in the evaluation of this work. The results reveal that good improvement can be attained in spectral efficiency at the expense of error rate performance when these functions are used. The results also reveal that the channel employing MSK system must be as linear as possible for the transmission of such signals. | ||||
