Abstract

In this paper we consider the application of per-survivor processing and diversity techniques to a partial response continuous phase modulation (PR-CPM) maximum likelihood sequence estimation (MLSE) receiver design. In particular, we consider practical implementation in a public safety narrowband radio environment. Frequency pulse truncation and tilted phase are used to reduce the number of states in the PR-CPM trellis with little loss in real world performance. Selection, equal gain and maximum ratio combining techniques are also considered to assess the practical benefit in system deployment.
