Minimum Euclidean distances of partial response multi-h phase-coded modulations with asymmetric modulation indices

A new concept of asymmetric modulation indices has recently been proposed and applied on full-response multi-h phase-coded modulations (MHPM) and improved error probability performance has been found. In this letter, a similar concept is applied to partial response MHPM and the minimum Euclidean distances for linear phase pulse function are evaluated to show further improvements.
