Digital Pulse Interval Modulation (DPIM) technique coded using a 1/3 code rate convolutional codes with 3constraint length is presented. The channel model used is that of the non-diffuse environment with no multipath induced dispersion. Coding DPIM results in an improved packet error rate performance compared with uncoded DPIM but at the price of increased bandwidth requirement while maintaining the same energy per symbol. Results also show that DPIM with one guard band does not significantly out perform DPIM without a guard band in a non-distorting channel.
