Abstract :
Multihop phase-coded modulation (MHPM) using asymmetric modulation indices corresponding to the bipolar data+1 and -1 is considered, and numerically obtained values of the minimum Euclidean distances for binary three-hop and four-hop schemes and power spectra for three-hop schemes are provided. It is shown that improved error probability is obtained compared to conventional MHPM with essentially no bandwidth expansion
