【摘要】 为解决通信的同时测定信号方位及通信与定位综合问题,提出了一种载有方位信息的数字时空调制技术,其调制信号是一个随接收机方位角变化而变化的非正交信号空间.设计了信号的调制和编码方案,研究了数字调制信号的载波提取和相干接收问题,给出了高斯信道下相干接收的误比特率和测向精度仿真结果.更多还原

【Abstract】 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.更多还原
