Abstract

An overview of some recent results for multi-h phase-coded modulation (MHPM) schemes is provided. These schemes offer power and bandwidth efficiency where time-varying modulation indices are used. Following a brief description of the structure of MHPM, its fundamental properties (e.g., minimum Euclidean distance and power spectra) are described. Decoding and demodulation of MHPM also are discussed. and some results on synchronization are summarized. MHPM combined with convolutional codes, asymmetric modulation indices, or nonuniform mapping are investigated.<>
