Next generation communication systems will be expected to operate under environment with high-speed motion and increasing
number of antennas where it will be difficult or even impractical to estimate the real-time channel coefficients. For this
reason, the DSTM (differential space time modulation) and USTM (unitary space time modulation) approaches that do not require
the channel estimation became hot topics in recent years. In this paper, we propose a general approach to designing high spectral-efficiency
signaling schemes. A novel modulation, dual constellations space-time modulation (DCSTM), is derived by extending DSTM and
USTM theoretically. DCSTM preserves the good features of USTM such as low error rate and the capability of being demodulated
without channel estimation. At the same time, it enhances the spectral efficiency and reduces the complexity of the modulation/demodulation.
It can be adapted to different data rates and thus has a wider applicable area. Simulation results verify the theoretical
analysis and the design of the new modulation method. |
