Carrier Synchronization and Coherent Demodulation of Space-Time Modulation Carrying with Azimuth Message

To solve integration of communication and radiolocation or to find angle of arrived signal while communicating, a new spacetime modulation carrying with azimuth message was proposed. The modulation has a nonquadrature signal space which varies with the azimuth of receiver. This paper presented the schemes to modulate signal, to code statue, to recover carrier and to receive message coherently. The performances of bit error rate and directionfinding with the modulation through Gaussian channel were investigated.
