Research on M-ary Spread Spectrum Space-time Coded Communication
We proposed a scheme combining space-time coding with M-ary Spread Spectrum over slow fading channel in this paper,In the scheme,space-time code is applied to chips of spread spectrum code directly.Compared to conventional space-time coded spread spectrum scheme,the scheme has shorter decoding delay because both detection and decoding can be completely performed within one symbol period.And more,the system has lower complexity because it is free of decision of space-time decoding,which is easy to achieve.Simulation demonstrate that the scheme is more power-efficient than conventional BPSK DSSS space-time coding scheme and it can get more space diversity gains over time selective fast fading condition.
