Abstract EN
Recently, polynomial phase modulation (PPM) was shown to be a power- and bandwidth-efficient modulation format.
These two characteristics are in high demand nowadays specially in mobile applications, where devices with size, weight, and power (SWaP) constraints are common.
In this paper, we propose implementing a full-diversity quasiorthogonal space-time block code (QOSTBC) using polynomial phase signals as modulation format.
QOSTBCs along with PPM are used in order to improve the power efficiency of communication systems with four transmit antennas.
We obtain the optimal PPM constellations that ensure full diversity and maximize the QOSTBC's minimum coding gain distance.
Simulation results show that by using QOSTBCs along with a properly selected PPM constellation, full diversity in flat fading channels and thus low BER at high signal-to-noise ratios (SNR) can be ensured.
More importantly, it is also shown that QOSTBCs using PPM achieve a better error performance than those using conventional modulation formats.
